Error: FirebaseApp with name {project_number} doesn't exist. Avilable app names: [DEFAULT]

Hi everyone, I'm trying to update both messaging and app packages. But when my app tries to firebase.messaging().getToken() I get this error. In the previous package version that I had installed it didn't happen.

I checked my google-services.json and it's ok. It has to be related to the update.

Can someone help me?

Thank you!

EDIT 1: I forgot to mention that only happens in android devices

From what version to what version? I suspect you crossed a major version boundary that had breaking changes which affected your project, and you may find migration information in the CHANGELOG file?

[adriangiulianotucci]

Yes you are right I’m doing a huge upgrade from the following versions to the latests:

"@react-native-firebase/app": "8.0.0",
"@react-native-firebase/messaging": "7.2.1"

But I’ve read every breaking change and I didn’t find anything. Maybe I can try upgrading in smaller versions…

My guess is the scoped token API changes? https://github.com/invertase/react-native-firebase/blob/main/CHANGELOG.md#breaking-changes-3

I think I've figured it out, I had 2 instances of the same app installed as different apps. I deleted one of them and started working I'm not sure why.

Thanks @mikehardy for your help!
