The error message you are encountering, "invalid_grant: The authorization code is invalid or has expired," typically indicates that the authorization code used in your request is either incorrect or has exceeded its validity period. This can happen for several reasons, including:
- The authorization code was not generated correctly.
- The authorization code has already been used and cannot be reused.
- The authorization code has expired due to time limits set by the authorization server.
To resolve this issue, you should ensure that you are using a valid and fresh authorization code. If necessary, re-initiate the authorization process to obtain a new code.
