Hello,
We are currently facing an issue with Apple Sign In that only occurs very rarely, and that for some reason mainly affects the Apple Review team, as everyone in the company can register with their personal Apple Account, and we can see multiple users in production using Apple Login.
The problem is that when our BackEnd tries to validate the information on https://appleid.apple.com/auth/token we receive a "{"error":"invalid_request"}". We have no idea what is causing this intermittent issue and we currently have no way to reproduce it.
We have been loging both succesull request and failing request and all look very simmilar and we have no ideia what may be causing the 400
here is an example of a curl that generated the problem
curl --location 'https://appleid.apple.com/auth/token'
--header 'Accept: application/json'
--header 'Content-Type: application/x-www-form-urlencoded'
--data-urlencode 'client_id=----SECRET----''
--data-urlencode 'client_secret=----SECRET----'
--data-urlencode 'grant_type=authorization_code'
--data-urlencode 'code=----SECRET----''
--data-urlencode 'redirect_uri=----SECRET----''
Any ideia what may be causing this?
