Cloud function while trigger - testing error

[pratikdhavale]

Getting output while testing the function

stopInstancePubSub
u3sbsgzeovt3
TypeError: callback is not a function at exports.stopInstancePubSub (/srv/functions/index.js:53:5) at Promise.resolve.then (/srv/node_modules/@google-cloud/functions-framework/build/src/invoker.js:330:28) at process._tickCallback (internal/process/next_tick.js:68:7)

Referring the doc/code from here: https://cloud.google.com/scheduler/docs/start-and-stop-compute-engine-instances-on-a-schedule

Same issue, followed the documentation to a t and get the error "TypeError: callback is not a function" when running the following part

gcloud functions call startInstancePubSub \
    --data '{"data":"eyJ6b25lIjoidXMtd2VzdDEtYiIsICJsYWJlbCI6ImVudj1kZXYifQo="}'

I also face the same issue. I was trying to migrate the code, using this doc https://cloud.google.com/functions/docs/migrating/nodejs-runtimes but ends with no luck. Please. Help.

Start Compute Engine:

var http = require('http');
var Compute = require('@google-cloud/compute');
var compute = Compute();
exports.startInstance = function startInstance(req, res) {
var zone = compute.zone('instance zone here');
var vm = zone.vm('instance name here');
vm.start(function(err, operation, apiResponse) {
console.log('instance start successfully');
});
res.status(200).send('Success start instance');
};
package.json:

{
"name": "sample-http",
"dependencies": {
"@google-cloud/compute": "0.7.1"
},
"version": "0.0.1"
}
Stop Compute Engine:

var Compute = require('@google-cloud/compute');
var compute = Compute();
exports.stopInstance = function stopInstance(req, res) {
var zone = compute.zone('instance zone here');
var vm = zone.vm('instance name here');
vm.stop(function(err, operation, apiResponse) {
console.log('instance stop successfully');
});
res.status(200).send('Success stop instance');
};

I found working solution here https://medium.com/google-cloud/start-stop-compute-engine-instance-from-cloud-function-bf9ae5199609

Thanks HuanTing Chen

But still the code provided in GCP docs is not working.

@djmailhot Could you have a look, you authored the sample. Thank you!

[djmailhot]

@jpatokal seems like your code update has a bug.

[jpatokal]

Thank you for bringing this to my attention. It looks like the function signature has changed for NodeJS 8, and this was not caught by the unit tests. I'll update this repo shortly, but in the meantime, you can find a fixed version here:

https://github.com/jpatokal/nodejs-docs-samples/blob/4086fd02f2ce305f3b2b7c6f1ea8f6f685b10ff3/functions/scheduleinstance/index.js

[jpatokal]

This should be fixed now.
