I have a function that is fired on a onUpdate trigger from my cloud firestore database. The function not being called at all when I change my database.
I did not deploy the function using firestore CLI, instead I deployed it using the GCP Console.
Here is the function:
exports.NotificationListener = functions
.firestore
.document('users/{userId}')
.onUpdate((change, context) => {
const userId = context.params.userId.toString();
const eventId = context.eventId;
console.log('EventId:' + eventId);
console.log('Change in:' + userId);
return 200;
});
Here is the deployment information from the GCP console (showing the trigger):
Finally, here is the Cloud Firestore schema:
I want to monitor any changes to any "USER" in the collection: "/user", hence I am using "user/{userId}".
Why is this function not being called when I change the database ?
EDIT 1
A little information about my environment:
I have my entire project core in a TypeScript file. I have over 40 HTTPS triggered functions that are currently online.
I add a new function in my TS file, then I do a npm run build
to compile and get the JS file.
Finally, I go to Google Cloud Console and create a function and choose "Zip Upload" and upload the compiled JS file (obviously, along with the required JSON files for getting Database URL, Authentication etc.)
This approach works perfectly fine, at least for HTTP triggered firestore functions.
Now I repeated the same steps as above for the onUpdate
trigger and just instead of choosing HTTP trigger, I chose Cloud Firestore
trigger. The trigger information can be found above in the screenshot.
onUpdate is not being fired on DB changes.
EDIT 2
My event trigger function NotificationListener
is showing up in the firebase console functions list along with my other 40 HTTPS functions. But it is not being called.
