Incorrect payload data format

When I am getting the token after login, But when I want to verify in jwt.io the payload data is something like this:
“{"id":"643da67379850�\u0012�\u0013\u001d\n\u0010P�\u0007.�+\u0018����n˽L���NL�\f�\b�^\u001c\b��M�\u000eMM\rL�\f�”

Hi @prisoner544,

Welcome to the Auth0 Community!

I understand you encountered issues decoding your access token namely with obscure characters for the “id” claim.

Firstly, would you mind providing me with the exact steps and code you used to get the access token?

And if possible, could you send me a direct message with an example of the access token with obscure characters?

Thanks,
Rueben
