java.lang.IllegalArgumentException: No enum constant com.google.firebase.ErrorCode.UNIMPLEMENTED

[cgdsyilmaz]

Hello,

We are receiving IllegalArgumentException while calling com.google.firebase.messaging.FirebaseMessaging#sendMulticast(com.google.firebase.messaging.MulticastMessage) method since 2024-08-12 13:44 GMT. We are using 9.1.1 version of firebase-admin dependency.

Here is the exception detail:

Is there a chance that a deprecated resource was deleted today? In any case, we are switching to the sendEachForMulticast method as suggested.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

same thing happening here as well. does anybody want to share any workaround?

tested upto 9.3.0 and still have no idea why the MessagingServiceErrorResponse's holding seemingly unintended status 'UNIMPLEMENTED'.

sendMulticast is unsupported since 22 july 2024 gradually they remove support from users.
you can check the issue #834 (comment)

Yes indeed! Thanks for clearly pointing that out 👍
..yet still com.google.firebase.ErrorCode.UNIMPLEMENTED shall be added I think.

FYI @GideonCallbus

FCM will start a gradual shutdown of deprecated APIs around July 22nd, 2024. After this date, deprecated services will be subject to a "flickering" process in which increasing numbers of requests will return error responses. During the gradual ramp-down period you can expect the following behavior and error responses to increase in frequency over time:

Thank you for pointing this out. However a smoother transition from the deprecated resource to the new one could have been planned.

Changing to the new sendEachForMulticast api fixed this, if anyone is still looking for a solution.

I am closing this issue as switching to sendEachForMulticast() is the right approach here
