I followed the different pages to deploy a voila ipynb app on heroku:
https://pythonforundergradengineers.com/deploy-jupyter-notebook-voila-heroku.html
https://medium.com/analytics-vidhya/deploying-jupyter-notebook-as-a-web-app-with-heroku-d157b68bcccc
https://github.com/voila-dashboards/voila-heroku
Unfoprtunately, it seems that there is a persisting bug this last month (saw here for instance https://forums.fast.ai/t/heroku-app-wont-deploy/92875/4)
You can find the github repo I am trying to deploy here:
https://github.com/vpicouet/fireball2-etc
The app is base on this Procfile
web: voila --port=$PORT --no-browser --enable_nbextensions=True notebooks/ETC.ipynb
Unfortunately I get this error

Do you know fow to solve this?
Thanks a lot!
I already tried some ideas on the web:
change
web: voila --port=$PORT --no-browser --enable_nbextensions=True notebooks/ETC.ipynb
by
worker: voila --port=$PORT --no-browser --enable_nbextensions=True notebooks/ETC.ipynb
The answer can be found here: issue 1047
From 0.3.0, Voila will not listen on all interfaces by default (#926) for security reasons. In the case of Heroku, you need to add --Voila.ip=0.0.0.0 to your command in the Procfile to make it work.

Have a working React App that can run locally using the command:
npm start
However, after deploying on Heroku, i receive an application error message.
The application URL is:

According to your application logs the line Starting the development server, indicates that the application is running on development mode which shouldn't happen as it is a production environment.
The reason,
According to https://devcenter.heroku.com/changelog-items/370
A Procfile is no longer required to run a Node.js app on Heroku. If no Procfile is present in the root directory of your app during the build process, we will check for a scripts.start entry in your package.json file. If such an entry is present, a default Procfile is generated automatically
$ cat Procfile
web: npm start
In your repository, since you have not specified a Procfile. Heroku automatically generates a Procfile that runs your app on development.
Currently, your react-app is treated as a regular node.js application as the node.js buildpack is used which is automatically inferred due to the presence of package.json in the root.
To fix this, you need to use the create-react-app-buildpack on Heroku.
Refer: https://elements.heroku.com/buildpacks/nhutphuongit/create-react-app-buildpack
I deployed a Python Flask app on Heroku but it failed to build because not finding the specified module : flask which was in the requirements though. The error is :
ModuleNotFoundError: No module named 'flask'
I checked Raja Simon's answer and used the $pip freeze > requirements.txt command. It gave logs quite longer but with the similar error at the end.
Here are the logs :

I understand what the errors are, but how can such a tiny tutorial app be causing a boot timeout (R10)?
How can I debug this better and fix the app so it runs?
When you deploy an app through heroku, it does not allow you to specify the port number.
In other words, you can not specify your web service's port number as 8000 or something else, heroku decides the port number in runtime.
so, you can not use the following code:
log.Fatal(http.ListenAndServe(":8000", router))
What you can do is, getting the runtime port of heroku.
In short, just use the following code:
log.Fatal(http.ListenAndServe(":" + os.Getenv("PORT"), router))
Your app needs to listen to all network connections. If it only listens on localhost, heroku's process watcher will not be able to detect that you bound the port, nor send requests to your app.
That means instead of:
http.ListenAndServe("127.0.0.1:"+port, nil)
You need to call:
http.ListenAndServe(":"+port, nil)

So, I am just trying to get a simple Heroku server running Dashing up. So far, I have the dashing and gemlock committed to heroku. Whenever I open the site, I get an error. My logs give me this:

A config.ru file was never created...I'm new to Ruby and Dashing and Heroku. I've even tried creating a blank config.ru, but even more errors occur...
Found the config file in anothjer directory somehow. Popped it in, it works!
