Hello dear people.

I tried to integrate Push Notifications into my Flutter App.

Everything works fine on Android/iOS Simulator + Testflight but as soon as I shipped my app into the app stores I get this error by trying to send a Push Notification via appwrite console.

TypeScript
Failed sending to target emq****5s5:APA91bFBm*****3b4fI with error: Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.
  • I use appwrite self-hosted 1.8.1
  • I use FCM (also for iOS)
  • Firebase Messaging is activated
  • FCM Provider is setted up in appwrite console (including the json from the google service account)
  • the .p8 file is uploaded into firebase project

I hope someone can help me here - I also didn't found something in the docker logs....

thanks, best regards

TL;DR
Developers experiencing an issue with sending Push Notifications via appwrite console after app store release. Error indicates missing authentication credential; solution involves supplying OAuth 2 access token, login cookie, or valid auth credential. Mention use of appwrite self-hosted 1.8.1, FCM, Firebase Messaging activation, FCM Provider setup in appwrite console, and upload of .p8 file to Firebase project. Further details needed; no solution directly provided in thread.
