Firebase functions pubsub trigger does not receive proper information

[szaleq]

I have a problem with firebase pubsub trigger - the function causes error in firebase-functions code because some param is undefined.

I published an issue infirebase-functions repo here but don't know it's a problem with firebase-functions or somewhere else...? It seems that the argument passed to the pubsub trigger is undefined instead of being an object with published message data.

I have a simple function using v2 pubsub trigger, which should capture published message and save it into firestore. The function looks like this:

const onProfileCreated = onMessagePublished(
    TOPIC_NAME,
    (event) => handleMessagePublished(event.data.message.json) // this function should just store message data in firestore
);

While working perfectly well in local development using firebase emulators, this function's code doesn't get executed when deployed because of an error in firebase-functions code:

TypeError: Cannot read properties of undefined (reading 'messageId')
    at new Message (/workspace/node_modules/firebase-functions/lib/v2/providers/pubsub.js:65:31)
    at func (/workspace/node_modules/firebase-functions/lib/v2/providers/pubsub.js:127:40)

Closing this as it seems like the firebase repo owners have asked for more debug info but the issue has been closed due to no response.
