I didn't using `jwt` package directly in `laravel`. I am using `passport`. They are using `jwt` — Senthurkumaran, Nov 25 '20 at 16:54
In your project `composer.json` add `"lcobucci/jwt": "3.3.3"` and execute `composer update`. — STA, Nov 25 '20 at 16:58
Thanks man. I downgrade to `lcobucci/jwt:3.3` It's working for me — Senthurkumaran, Nov 25 '20 at 17:15

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

Or, In config\jwt.php file Change :

'jwt' => Tymon\JWTAuth\Providers\JWT\Lcobucci::class,

to

'jwt' => Tymon\JWTAuth\Providers\JWT\Namshi::class,

Where is the config\jwt.php ? – Itay Moav -Malimovka Jun 29 '21 at 13:20
@ItayMoav-Malimovka on the same location where the `/config/app.php` located. – STA Jun 29 '21 at 14:16
@sta Missed the Laravel tag. I am using this lib through another system (oauth league). Ill find it ;-) – Itay Moav -Malimovka Jul 01 '21 at 01:33
First I tried "composer require lcobucci/jwt" but not working for me, then I tried composer require llcobucci/jwt": "3.3. Its working perfectly. Thanks @sta – Piyush Sapariya May 04 '22 at 07:39

As said before, lcobucci/jwt:3.4 is causing this issue, which can be solved by downgrading to 3.3.*. However, if you have declared something like this:

"lcobucci/jwt": "^3.3.1",

you need to remove the ^ because v3.4 would still be downloaded. Please keep in mind, using a newer version might be better because of bugfixes and other stuff, so make sure to update the respective logic to work with a newer version of the dependecy.

Thanks, i got this error today with Passport v7 and adding "lcobucci/jwt": "3.3.1" to composer.json solved it for me. – Miloslav Milo Janoušek Dec 04 '20 at 15:20
