Operation is not implemented, or supported, or enabled.

[Mariusz Kupczyk]

Hi Firebase team,

We've recently encountered an issue with the `.messaging().send()` method. The requests are returning the following error:

{

  "error": {

    "code": 501,

    "message": "Operation is not implemented, or supported, or enabled.",

    "status": "UNIMPLEMENTED"

  }

}

Additional details:

• Using firebase-admin version 12.5.0 and Node.js version 14.21.3
• This issue appeared suddenly in the last few days
• We've tried refreshing our private key JSON, but it didn't resolve the problem

Could someone please advise:

1. What does this error actually mean in this context?
2. How should we troubleshoot this situation?

Thank you in advance for your help!

Hello,

A couple questions/requests:

• Which admin SDK are you using? Node? Java? .NET?
• Please post your messaging send call method with all necessary context, redacting whatever you need to.

Regards,

Joe
