OSError: [Errno 75] Value too large for defined data type

Can you please advise? Many thanks!!

Hey,
You're encountering the OSError: [Errno 75] Value too large for defined data type error related to timestamps.
Could you please provide more details about the JWT token that triggered this error?
Specifically, the values of the iat and exp timestamps in the token payload would be helpful to diagnose the problem further.
