Getting invalid_grant when validating the authorization code

Pain

I’m trying to implement Sign in with Apple and it’s been going fine until I tried to validate the authorization code using the Web Service Endpoint – https://appleid.apple.com/auth/token.
The error I’m getting back from the request is invalid_grant.
If I decode the client_secret jwt that I created, it looks like this, which is what the documentation says it should look like. (I followed the documentation and still getting errors)
Any ideas? Thanks in advance.

I am facing the exact same problem. I am trying to integrate this in a Django project using this https://github.com/truffls/sign-in-with-apple-using-django, already asked this question there as well https://github.com/truffls/sign-in-with-apple-using-django/issues/2 .
Others are having the same problem - https://forums.developer.apple.com/thread/118135
I’ll reply if i’ll get it working.
