Pubsub onMessagePublished handler does not work

[szaleq]

[REQUIRED] Version info

node: 18

firebase-functions: 4.5.0

firebase-tools: 12.8.1

firebase-admin: 11.11.0

[REQUIRED] Test case

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
);

[REQUIRED] Steps to reproduce

Just create a function using onMessagePublished.

[REQUIRED] Expected behavior

I expect the function to get executed with the event containing published message data as a param.

[REQUIRED] Actual behavior

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)

Were you able to successfully deploy your functions?

Yes, I managed to successfully deploy the function, but needed to use gcloud CLI, because when using firebase deploy command, I received an error stating that it failed to create the topic (which is weird, because the topic was already created in pubsub and also the docs say that cloud functions will not create topics and topics should be present during deployment - which was fulfilled).

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @szaleq, I'm unable to reproduce the issue using the setup and versions you described above. Can you try deploying again with firebase deploy --debug and share with me the contents of the resulting firebase-debug.log?
