Error getting a Firebase function configured - Failed to configure trigger

I'm getting this error and I can't find why

Error:

Failed to configure trigger providers/cloud.firestore/eventTypes/[email protected]

Function:

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();

exports.newSubmit = functions.firestore
    .document('usersSubmit/{id}')
    .onCreate(() => {
        console.log('new document created');
    });

The collection usersSubmit does exist as a root collection. Is it my function or is Cloud Functions having a hard time?

Documenting another edge case that can cause trigger deployments to fail

I have a preferences subcollection in /users that has a single document with the user's uid as the doc id (for simplicity). I had my trigger configured as follows:

.document("/users/{userId}/preferences/{userId}")

It was working fine in the emulator, but when I deployed, I was getting a Failed to configure trigger error,

Turns out you can't use the same wildcard identifier twice in the path. I changed it to:

.document("/users/{userId}/preferences/{preferencesDocId}")

And the deployment succeeded with no errors.

Now that I think about it, it was a stupid mistake, but if you're doing what I did...don't.

Simple! I had to add a forward slash before the root collection.

.document('/usersSubmit/{id}')
