Error, Lcobucci\JWT\Signer\InvalidKeyProvided: It was not possible to parse your key

Question

I hope you are doing fine. I was working on Oauth passport laravel, it was working fine on my previouse machine but i had to switch machines.My new machine has php 8 and my laravel project is of 7.30.0 version and my lcobucci/jwt version is 3.3.3. When i try to hit register route on postman i get the following error

Lcobucci\JWT\Signer\InvalidKeyProvided: It was not possible to parse your key, reason: in file C:\Users\user\Documents\GitHub\myproject\vendor\lcobucci\jwt\src\Signer\InvalidKeyProvided.php on line 17

Answer 1

As you can see on https://packagist.org/packages/lcobucci/jwt#3.3.3, that JWT package is officially not compatible with PHP 8. You should upgrade it to a compatible version (at least v4), or downgrade your PHP version to v7
