Callback URL giving Client error: POST https://appleid.apple.com/auth/token resulted in a 400 Bad Request response: {"error":"invalid_client"}

Everything works fine except when landing on callback url the post request giving an error.

Client error: POST https://appleid.apple.com/auth/token resulted in a 400 Bad Request response: {"error":"invalid_client"}

This sounds like a configuration issue where your client ID in the app might not be matching the client ID you have registers with your Apple developer account?

[wamtengineers]

If Client ID I have put is Service identifier as per your instruction in the documentation. It is going through normal process when clicking apple icon here https://ignitefiringsystems.com/fireworks/login but after successful authentication it is showing error screen.

Thanks for clarifying. I will see if I can replicate this.

@wamtengineers Make sure that the Client ID in .env and client_secret.rb is the same, otherwise you'll get this error (only on the callback).

[wamtengineers]

Sorry! Could you please elaborate? I did not understand.

Ok I regenerated Client Secret and yes there was a mistake is Client ID parameter. now the error is gone. But I am receiving a null user object. This is debug output.

If this is happening, during development and testing, you will need to remove your signing-registration at https://appleid.apple.com, then re-register. Each time you fail/test the initial registration process, you will need to remove your app signing registration at apple.com in order to start from a blank slate. This error will always come up if your initial registration had any issues.
