While I run the command firebase deploy I get this error:

i deploying functions

i functions: ensuring necessary APIs are enabled...

i runtimeconfig: ensuring necessary APIs are enabled...

✔ runtimeconfig: all necessary APIs are enabled

i functions: preparing functions directory for uploading...

⚠ functions: failed to create function followerNotification

⚠ functions: HTTP Error: 400, The request has errors

⚠ functions: 1 function(s) failed to be deployed.

Functions deploy had errors. To continue deploying other features (such as >database), run:
firebase deploy --except functions

Error: Functions did not deploy properly.

Having trouble? Try firebase deploy --help

Everything else works without problems. Only when I trying to make something with Firebase Firestore.

This was happening to me too, then I realized that at the 2nd level, firestore only allows documents and not collections.

I was attempting to listen to this path:

/collection/document/{wildcard}

You can either to something like

/collection/{wildcard}

or

/collection/document/collection/{wildcard}

The problem is that you only reference a collection and not a document like:

exports.myFunctionName = functions.firestore

      .document('users/marie').onWrite((event) => {

        // ... Your code here

      });

You need to reference the document like:

exports.myFunctionName = functions.firestore

  .document('users/marie').onWrite((event) => {

    // ... Your code here

  });

You can also use a wildcard like:

exports.myFunctionName = functions.firestore

  .document('users/{userId}').onWrite((event) => {

    // ... Your code here

  });

It's described in here: https://firebase.google.com/docs/functions/firestore-events

Hope I could help

I had this problem as well. In my case it was because my trigger path had a trailing slash in the document path.

So changing:

functions.firestore

  .document('some_path/{pushId}/')

To:

functions.firestore

  .document('some_path/{pushId}')

Fixed it it for me. It seems like this is caused by a variety of issues and the firebase cli does not do a good job at explaining the reasons why.

The issue was probably caused by the length of the function name.

So, if the name is:

myFunctionsFromWorksWithCustumersTiggersTests

change for a shorter name, like:

WorkWithCustumers

I hope I helped.

My issue with the same error message was that Cloud Functions' pubsub doesn't seem to support topics with names beginning with numeral characters.

I had the same error when trying to publish a function listening to a Cloud pub/sub, that began with numerical characters.

exports.nightly_pruning = functions.pubsub.topic('24hr-tick').onPublish((event) => { 

    ... 

});

Fixed it by simply changing the name:

exports.nightly_pruning = functions.pubsub.topic('nightly-tick').onPublish((event) => { 

    ... 

});
