I am trying to debug my js code the runs on firebase functions.
My steps were:
install from functions
npm install --save #google-cloud/debug-agent
added index.js:
require('#google/cloud-debug').start();
when I tryed to run
firebase deploy --only functions
got an error :
Error: Error parsing triggers: Cannot find module '#google/cloud-debu
g'
Try running "npm install" in your functions directory before deployin
try: ndb firebase serve
debugger breakpoints are hit with stack traces visible, note it's a little slow so give the debugger time to instrument the child processes
Additionally I was able to debug cloud functions in isolation using (caps for removed values):
GCLOUD_PROJECT=THE-FIREBASE-PROJECT node --inspect-brk /path/to/functions-framework --target FUNCTION-NAME --port=5000
where functions-framework simply expands to the full path for the installed functions-framework (global in my case) and the working directory contains the target index.js for functions.
Alternately when or where the FIREBASE_CONFIG is needed try this format adjusted to fit:
FIREBASE_CONFIG="{\"databaseURL\":\"https://YOUR-FIREBASE-PROJECT.firebaseio.com\",\"storageBucket\":\"YOUR-FIREBASE-PROJECT.appspot.com\",\"projectId\":\"YOUR-FIREBASE-PROJECT\"}
https://github.com/GoogleChromeLabs/ndb
https://cloud.google.com/functions/docs/functions-framework
https://github.com/GoogleCloudPlatform/functions-framework-nodejs/issues/15
The addition to index.js should be:
require('#google-cloud/debug-agent').start();
or better:
require('#google-cloud/debug-agent').start({ allowExpressions: true });
We recently renamed the module, and it is possible that the instructions you are following are partially out of date. Can you point us to the instructions you have been following?
Also note that support for debugging cloud functions is experimental at this point. There are certain cases (dependent on the traffic to the function) where you function may finish before the debug-agent has a chance to initialize/register. We're currently looking into how to address this.

I'm trying to setup Facebook Duckling on Windows 10.
When I execute: stack exec duckling-example-exe it produces the following error:
duckling-example-exe.EXE: /etc/zoneinfo/: getDirectoryContents:findFirstFile: does not exist (The system cannot find the path specified.)
I don't understand why I'm getting this error since I followed the recommendation on this GitHub thread which suggests replacing "/usr/share/zoneinfo/" in Duckling/exe/ExampleMain.hs with a link to a folder containing the zoneinfo files. You can see I replaced the path as suggested in the screenshot below:
I also tried adding a double slash as seen below - but it didn't help:
I tried with forward slash instead but this didn't help either:
Moreover, I don't understand where the path: /etc/zoneinfo/ is coming from, if the path is no longer present in ExampleMain.hs? Where is the compiler pulling the path from?
Thanks!
You need to run stack exec duckling-example-exe in the directory where the stack.yaml and project.yaml files of the duckling source code is that you are trying to modify. Otherwise it will use the version of duckling from stackage without your changes.
I am a newbie in go and go-swagger. I am following steps in Simple Server tutorial in goswagger.io.
I am using Ubuntu 18.04, swagger v0.25.0 and go 1.15.6.
Following the same steps, there are a few differences of the files generated. For instance, goswagger.io's has find_todos_okbody.go and get_okbody.go in models but mine does not. Why is that so?
Link to screenshot of my generated files vs
Link to screenshot of generated files by swagger.io
Starting the server as written in the tutorial go install ./cmd/todo-list-server/ gives me the following error. Can anyone please help with this?
# my_folder/swagger-todo-list/restapi
restapi/configure_todo_list.go:41:8: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
restapi/configure_todo_list.go:42:6: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
The first step in goswagger.io todo-list is swagger init spec .... Which directory should I run this command in? I ran it in a newly created folder in my home directory. However, from the page, it shows the path to be ~/go/src/github.com/go-swagger/go-swagger/examples/tutorials/todo-list. I am not sure whether I should use go get ..., git clone ... or create those folders. Can someone advise me?
Thanks.
This is likely the documentation lagging behind the version of the code that you are running. As long as it compiles, the specific files the tool generates isn't so crucial.
This is a compilation error. When you do go install foo it will try to build the foo package as an executable and then move that to your GOPATH/bin directory. It seems that the generated code in restapi/configure_todo_list.go isn't correct for the operations code generated.
All you need to run this tutorial yourself is an empty directory and the swagger tool (not its source code). You run the commands from the root of this empty project. In order not to run into GOPATH problems I would initialise a module with go mod init todo-list-example before doing anything else.
Note that while the todo-list example code exists inside the go-swagger source, it's there just for documenting example usage and output.
What I would advice for #2 is to make sure you're using a properly released version of go-swagger, rather than installing from the latest commit (which happens when you just do a go get), as I have found that to be occasionally unstable.
Next, re-generate the entire server, but make sure you also regenerate restapi/configure_todo_list.go by passing --regenerate-configureapi to your swagger generate call. This file isn't always refreshed because you're meant to modify it to configure your app, and if you changed versions of the tool it may be different and incompatible.
If after that you still get the compilation error, it may be worth submitting a bug report at https://github.com/go-swagger/go-swagger/issues.
Thanks #EzequielMuns. The errors in #2 went away after I ran go get - u -f ./... as stated in
...
For this generation to compile you need to have some packages in your GOPATH:
* github.com/go-openapi/runtime
* github.com/jessevdk/go-flags
You can get these now with: go get -u -f ./...
I think it's an error of swagger code generation. You can do as folloing to fix this:
delete file configure_todo_list.go;
regenerate code.
# swagger generate server -A todo-list -f ./swagger.yml
Then, you can run command go install ./cmd/todo-list-server/, it will succeed.
I have a React application with ApolloClient with Apollo-Link-Schema. The application works fine locally but in our staging environment (using GOCD), we get the following error:
Uncaught Error: Cannot use e "__Schema" from another module or realm.
Ensure that there is only one instance of "graphql" in the node_modules
directory. If different versions of "graphql" are the dependencies of other
relied on modules, use "resolutions" to ensure only one version is installed.
https://yarnpkg.com/en/docs/selective-version-resolutions
Duplicate "graphql" modules cannot be used at the same time since different
versions may have different capabilities and behavior. The data from one
version used in the function from another could produce confusing and
spurious results.

Dependencies are installed with yarn, I've added the resolutions field to the package.json.
"resolutions": {
"graphql": "^14.5.8"
},
I've checked the yarn.lock and can only find one reference for the graphql package.
npm ls graphql does not display any duplicates.
I thought maybe its a build issue with webpack - I have a different build script for staging, but running that locally I am still able to get the react application to run with that bundle.
Can anyone suggest anything else to help me fix this?
I managed to find the cause of the issue, if this helps anyone else. The issue is not to do with duplicate instances of the package at all, this is a false positive triggered by us using webpack's DefinePlugin to set the process.env.NODE_ENV to staging for our staging build.
However, in webpack the mode (see https://webpack.js.org/configuration/mode/), which sets the process.env.NODE_ENV, only accepts none, development and production as valid values. This was triggering an env check in the graphql package to fail and trigger this error message.
In our case, we need to differentiate between staging and production as our API endpoint differs based on this, but the solution we implemented is to not rely on the process.env.NODE_ENV, but to assign a custom variable on build (e.g. process.env.API_URL)
I would try to replicate the error locally and debug it:
try this:
rm -rf node_modules yarn.lock
# also remove any lock files if you have package-lock.json too
yarn install
# build the project locally and see if you got the error
I got this problem one time where I was working with Gatsby and 2 different themes where using different versions of GraphQL. Also be more explicit with the version (without caret) and check if the error persist.
do you have a repo youc an share? that would also help us to help you :)
While changing NODE_ENV to production might solve the issue, if you have different variables for each environment and don't want to mess with your metrics this is not an ideal solution.
You said you use webpack. If the build with the issue uses some kind of source-map in your devtool, you might want to disable that to see if the problem persists. That's how I solved this without setting my NODE_ENV to production.
I had a similar problem when trying to run Apollo codegen and was able to fix it by deduping my npm packages. Run this:
rm -rf node_modules && npm i && npm dedupe
I was having this problem so I switched to yarn, and after deleting node_modules and npm lockfile, then running yarn, the problem went away :-).
I ended up here because I use the AWS CDK and the NodejsFunction Construct. I was also using bundling with minify: true.
Toggling minify to false resolved this for me.
I'm working through the J primer, and getting stuck when it comes to the load command.
In particular, there are times when the next step in a tutorial is load 'foo' and I'll get an error like the following:
load 'plot'
not found: /users/username/j64-801/addons/graphics/plot/plot.ijs
|file name error: script
| 0!:0 y[4!:55<'y'
When I do ls /users/username/j64/addons/ I only have config and ide in there, so it's sensible that graphics is not found.
My question:
if given an example that says load 'foo', how do I go about finding and installing foo?
I'd recommend simply installing all the JAL packages ("Addons"). There aren't too many, so the download won't take long, and you'll have access to everything you need to run the Labs, Wiki examples, and any code posted by the community (e.g. on the J Forums).
To install all available Addons, type the following into Jconsole (you could theoretically type it into JHS or JQT instead, but since those are distributed as Addons, you might not be able to upgrade them while they're running):
load'pacman' NB. J PACkage MANager
install'all'
The package manager will start running, and you'll see output like:
Updating server catalog...
Installing 52 packages
Downloading base library...
Installing base library...
Downloading api/gl3...
Installing api/gl3...
Downloading api/ncurses...
Installing api/ncurses...
Then stop and restart Jconsole, and run:
load 'pacman'
'update' jpkg 'all'
To make sure all recursive dependencies were satisfied and all packages are up to date (in particular, the base library). Ultimately, you want to see something like:
Updating server catalog...
Local JAL information was last updated: <datetime>
All available packages are installed and up to date.
Then stop & restart J one last time. When that's done, you should have everything you need to run the Labs.
To answer your final question, if you see a line like:
load'foo'
The first thing you should do is run getscripts_j_ 'foo'. In your example:
getscripts_j_ 'plot'
+--------------------------------------------------------------+
|c:/users/user/j64-801/addons/graphics/plot/plot.ijs|
+--------------------------------------------------------------+
Here, you can see the fully-qualified path of where J expects the package to live.
In particular, you can see it where it is relative to the addons directory, which will always be in the form addons/category/module/foo.ijs. The category and module name indicate which addon you need to install, so all you have to do pick the desired entry from the catalog visible in the package manager.
Trying to add new helpers to docpad.coffee I'd like to debug these.
Having setup node inspector as outlined in http://docpad.org/docs/debug I expected the console to show logs when used with e.g.
getOutDir: (inPath) ->
console.log('inPath')
How to set breakpoints to helper methods in docpad.coffee?
How to log from docpad.coffee?
The instructions on docpad.org for node-inspector are incorrect (they are being worked on). You can't just run docpad-debug because that runs the globally installed version of docpad which confuses the debugger. Instead run the local copy of docpad-debug from your node-modules folder:
./node_modules/.bin/docpad-debug run
How to log from docpad.coffee?
docpad.log("info", "... your log info here ...")
Other log levels are "warn" and "error".
