Create pubsub function with dead letter

[Xaviou1003]

Hello,

Not really a bug, it is more an improvement.

I search a way to configure a dead letter topic to the subscription that is automatically created when I deploy a new pubsub cloud function.
Actually my workaround is to configure the dead letter after cloud function creation.

I saw this issue but there is not a fix.

[REQUIRED] Version info

node:
16.16.0

firebase-functions:
4.1.0

firebase-tools:
10.2.0

firebase-admin:
11.0.1

[REQUIRED] Test case

Implement a pubsub cloud function with firebase-functions.
Deploy it with firebase cli.
There is no way to define a dead letter.

[REQUIRED] Steps to reproduce

Implement a cloud function with a pubsub trigger
functions .region('europe-west3') .runWith() .pubsub.topic('SignalEvent') .onPublish(...)

----> No option to configure a dead letter

[REQUIRED] Expected behavior

I want to configure dead letter parameters with a specific option.

[REQUIRED] Actual behavior

We can't configure dead letter topic and other dead letter parameters.

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.

I found a way to do what I want.
This post and this article save me.
