I am new to parse and facing issue don't know why this happens.
I have deployed default hello function on parse and i am calling it using parse api but response always return function name.
below is my deployed method
Parse.Cloud.define("hello", function (request, response) {
response.error("Hello World");
});
this is url that i am calling https://api.parse.com/1/hooks/functions/hello
and this is response
{
"results": [
{
"functionName": "hello"
}
]
}
it return function name instead of hello world. what is i am doing wrong?
You're using the wrong URL. This is a cloud function, not a web hook. The URL should be:
https://api.parse.com/1/functions/hello

Problem
I was trying to use 'aws-amplify' GET API request with query parameters on the client side, but it turned out to be Request failed with status code 403, and the response showed:
"message":"The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.
Note: React.js as front-end, Javascript as back-end.
My code
Front-end
function getData() {
const apiName = 'MyApiName';
const path = '/path';
const content = {
body:{
data:'myData',
},
};
return API.get(apiName, path, content);
}
Back-end
try {
const result = await dynamoDbLib.call("query", params);
} catch (e) {
return failure({ status: false });
}
What I did to debug
The GET lambda function works fine in Amazon Console (Tested)
If I change the backend lambda function so that the frontend request can be made without parameters, i.e. return API.get(apiName, path), then no error shows up.
My question
How can I make this GET request with query parameters works?
I changed GET to POST (return API.post()), everything works fine now.
If anyone can provide a more detailed explanation, it would be very helpful.
I keep getting this Vue error: "ReferenceError: response is not defined" but when I check in the console, the data is all there.
I intend to use the data from the response to make pagination. Thanks in advance.
Methods
getAllUserData(){
let $this=this;
axios.get('api/members/getAllMembersData').then(response=>this.members=response.data.data);
$this.makePagination(response.meta,response.links);
},
makePagination(meta,links){
let pagination={
current_page:meta.current_page,
last_page:meta.last_page,
next_page_url:links.next,
prev_page_url:links.prev
}
this.pagination = pagination;
}
axios.get() is an async function. The code that follows this function will not be executed after the ajax request completes, but long before that. Because of this, the variable response does not exist yet.
All code that has to be executed when the ajax call completes has to be put in the .then() function of the call.
getAllUserData(){
axios.get('api/members/getAllMembersData').then(response => {
this.members = response.data.data;
this.makePagination(response.data.meta, response.data.links);
});
},
Your response is still inside the axios get method, therefore the makePagination function has to be called inside axios method as well (inside .then())
getAllUserData(){
let $this=this;
axios.get('api/members/getAllMembersData').then(response=>
this.members=response.data.data
$this.makePagination(response.data.meta,response.data.links);
},
makePagination(meta,links){
let pagination={
current_page:meta.current_page,
last_page:meta.last_page,
next_page_url:links.next,
prev_page_url:links.prev
}
this.pagination = pagination;
}
I am new to serverless. I want to fetch data from google. I am using Google Custom Search engine. Although I got results when I run locally. But when I deploy to AWS Lambda I am getting "Internal Server Error". Can anyone help me to fix the issue?
'use strict';
var request = require('request');
module.exports.get = (event, context, callback) => {
request('https://www.googleapis.com/customsearch/v1?q=Serverless+AWS+Lambda&cx=xxxxxxxxxxx&key=API_key&num=10', function (error, response, body) {
if (!error && response.statusCode == 200) {
callback(null, response);
console.log(body);
} else {
console.warn(error);
}
});
};
I want a json output. I would like to save that result
Internal Server Error mostly points out that your lambda code could not be executed correctly. Did you pack all your dependencies (node_modules) within the ZIP file you provide to AWS lambda (e.g. request ?)
I have some web-enabled actions that are exposed through API Connect in IBM Cloud Serverless Functions.
Some of my actions use request-promises to call external REST services and I need to be able to catch an error and respond with an appropriate status-code to the caller.
Since the actions are web-enabled, the documentation indicates that I can use an annotated JSON to set the headers, status-code and body of the response. But it seems that, seems the API expects to always get a Content-Type=application/json, the response processor is failing to understand my annotations in the case of an error.
I tried the following without success:
let rp = require('request-promise');
function main(params){
//setup options
return rp(options).then(
res => {
return res;
}
).catch(
err => {
return { error: { statusCode:err.statusCode } }
}
);
}
Another variation:
let rp = require('request-promise');
function main(params){
//setup options
return rp(options).then(
res => {
return res;
}
).catch(
err => {
return { statusCode:err.statusCode }
}
);
}
The problem is that the status-code I always get is 200... I also tried to change the runtime to node8.0 without success.
Thanks!
I found the answer myself :)
In order to get the status-code and headers, one must set the field Response Content Type to `Use "Content-Type" header from action", while setting up the mapping between the API call and the action....
I wrote this cloud funtion for demo purpose.
Parse.Cloud.define('hello', function(req, res) {
res.success("hi");
});
But it always returns this error message
{
"code": 141,
"error": "res.success is not a function"
}
What's wrong?
Starting parse server 3.0 there is no response object anymore. Simply return the value and it will work.
Parse.Cloud.define(‘hello’, (req) => {
return ‘ok’;
});
