Getting SenderIdMissmatch error when trying to send notification via FCM #169

Closed bnoffer closed 4 years ago

bnoffer commented 4 years ago

Hi everyone, I working on implementing FCM on our server and I followed the Firebase Guide for FCM to setup the FirebaseApp instance. You can see the full implementation here:: https://github.com/real-digital-Mobile-Apps/net-core-push-notifications/blob/feature/RefactoringMerge/CorePush/Google/FcmSender.cs

I found a similar issue for the GO SDK: https://github.com/firebase/firebase-admin-go/issues/248 And I added the permission mentioned in the last comment, but still no luck. I am always getting the SenderIdMissmatch error from the SDK which is related to a HTTP Forbidden error from the aPI.

I also verified that the JSON that is passed as part of the constructor is correct and valid, the SDK is initialized without errors as well.

It typically means your authorization credential do not match the FCM token that you're trying to send notifications to. Most likely they are from two different projects.

I will close this since there's no action item I can see for the SDK implementation. If you continue to experience issues with this, please contact us via Firebase support.

How can that happen if everything is originating from the same Firebase project? I checked this more then twice to make sure that I have the correct configurations loaded on the server and app.

@bnoffer it's hard to tell, since we have no insight to how your tokens were generated, or how they were passed to the server-side code. I'd advise you the following course of action:

  1. Log the device tokens for which this error occurs.
  2. File a support ticket and indicate your project ID and the tokens that result in the error: https://firebase.google.com/support

You need to get the services JSON from the Firebase project itself. I thought wrong and got it from the Google API console after enabling Frirebase API.

The link to get the correct services JSON is here. The YOUR_PROJECT_NAME_HERE is the Google given project name.
