Method Laravel\Passport\Bridge\AccessToken::__toString() must not throw an exception, caught InvalidArgumentException error after upgrading

Question

I'm getting error mentioned above after upgrading to laravel 8 and laravel/passport 10.x. Did anyone face the problem?

Actual stacktrace: Symfony\Component\ErrorHandler\Error\FatalError: Method Laravel\Passport\Bridge\AccessToken::__toString() must not throw an exception, caught InvalidArgumentException: It was not possible to parse your key, reason: error:09091064:PEM routines:PEM_read_bio_ex:bad base64 decode in file /Users/<path>/vendor/league/oauth2-server/src/ResponseTypes/BearerTokenResponse.php on line 0

I tried creating user and login in and It is working ie creating record in db, It just the problem while sending response.

I was facing such a problem after running composer update where the third-party package lcobucci/jwt was updated. It was fixed after downgrading the version of lcobucci/jw to 3.3.3 by the following command:

composer require lcobucci/jwt 3.3.3
