In config\jwt.php file
Change 'jwt' => Tymon\JWTAuth\Providers\JWT\Lcobucci::class, to 'jwt' => Tymon\JWTAuth\Providers\JWT\Namshi::class,
=> It works for me <3

lcobucci/jwt:3.4 has this problem, composer require lcobucci/jwt:3.3 can resolve it.

How to fix for Lumen ?

[mstaack]

@wasddsaw publish jwt config file and load it in your bootstrap file with $app->configure()
-> https://github.com/laravel/lumen/blob/8.x/bootstrap/app.php#L62

In the meantime for those like me who uses lcobucci/jwt as a dependency of leage/league/oauth2-server or laravel/passport you can explicitly require the version 3.3.3 of the lcobucci/jwt package (until a better solution comes up) by executing:

composer require lcobucci/jwt:3.3.3 && composer update

It's not working for me, the lib used is "tymon/jwt-auth": "1.*"

I received the error: Could not create token: Implicit conversion of keys from strings is deprecated. Please use InMemory or LocalFileReference classes

I change my php.ini adding in the error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE & ~E_USER_DEPRECATED and keep not working.

question is what are the content of your composer.lock for lcobucci/jwt

Hi @dcyou , thanks for reply, my content in the composer.lock is:

"url": "https://github.com/lcobucci/jwt.git",
                "url": "https://api.github.com/repos/lcobucci/jwt/zipball/c1123697f6a2ec29162b82f170dd4a491f524773",
                "lcobucci/jwt": "^3.2"

[dcyou]

I think you don't run that command composer require lcobucci/jwt:3.3.3 if you ran that command you also should have "lcobucci/jwt": "3.3.3", in your require of composer.json

[bbprojectnet]

Any solution for branch 2.0?

[serdud]

Any solution for branch 2.0?

downgrade lcobucci/jwt to 3.3.3

[specialtactics]

Apart from downgrading, what's the longer term solution and does package author need help to implement?

Do we need to update the package for compatibility ?

That worked. I am using Laravel 8 👍

[lcobucci]

I change my php.ini adding in the error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE & ~E_USER_DEPRECATED and keep not working.

All Laravel versions override the server error_reporting configuration. I've created laravel/framework#35381 to address this issue and not break apps on deprecation messages from any library.

I really hope that gets merged and helps you all 👍

[tymondesigns]

Just catching up on all this. Looks like an upgrade to v4 is necessary, so will work on that asap. Thanks all!

[lcobucci]

@tymondesigns feel free to ping on PRs about this, would gladly help reviewing them 👍

Please check your PHP version requirements, v4 is PHP 7.4+ only. If need to support older PHP versions, you'd need to use ^3.4 || ^4.0 as version constraint. https://lcobucci-jwt.readthedocs.io/en/stable/upgrading/ should help you to achieve that.

Thanks, I think the best course of action is to restrict the version to <3.4 for now. I can address the v4 upgrade in the 2.0 branch, where php 7.4 is the minimum.
