Seeing a similar issue with Laravel 8 and passport 10.2

Trying to upgrade from PHP 7 to PHP 8. Is how we stumbled across this.

[lcobucci]

And that same message is happening? Is it possible that you have version 3.4 also installed?

[lcobucci]

Perhaps opcache?

any update ?

[farmani]

one of your dependencies rely on older version of lcobucci/jwt

As we found out in #838 the Auth0 SDK v7 (https://github.com/auth0/auth0-PHP/blob/7.x/composer.json#L17) requires a library which is a fork of an old an unmaintained version of this library to provide support to PHP 8 (and it seems like the conflicts section was not updated on that fork).

The v8 of that SDK solves the incompatibility by removing dependencies.
