Summary
Bug
When the
force_pkce
option is enabled for a public client, and the authorization code request doesn't include a code_challenge, the error message returned is"The authorization server encountered an unexpected condition which prevented it from fulfilling the request."
Root cause
[#1705] didn't add the error message in the locales.
Fix
Base on RFC https://datatracker.ietf.org/doc/html/rfc7636#section-4.4.1, we should return an "invalid_request" error with a proper description. I added a new entry for the error message and included a test to verify the proper message is returned.
