are you already run command php artisan jwt:secret to generate jwt secret key in your heroku?

[shantudash]

@muhtarudinsiregar yes , already did

[StevieDC]

Sorry @StevieDC I did not find any solution either. if you found any solution please let me know

[KonstantinLapkovsky]

@shantudas @StevieDC I met with a similar problem too. I changed the 'JWT Provider' to 'jwt' => Tymon\JWTAuth\Providers\JWT\Lcobucci::class in the jwt.php file and cleared the config cache.

Controller constructor:

public function __construct(JWTAuth $jwtAuth)
{
    $this->jwtAuth = $jwtAuth;
}

Did this work? I am stuck.

[shantudash]

nope @dagenius007

[dagenius007]

@shantudas Do you have a jwt.php in your config?

[StevieDC]

As mine was working locally I decided to bypass Git and Ftp everything up to the server (except .env). It then worked on the live server!

You might need to clear your cache after running php artisan jwt:secret. I clear laravel cache using php artisan clear-compiled && php artisan optimize

[egiesemka]

stop php artisan serve, and start again

[CodyFortenberry]

I was having a problem on Fortrabbit. The fix for me was to upload my .env file. It was in the gitignore so it was not committed. At the bottom of the .env file is the jwt secret.

[tymondesigns]

This error happens when JWT_SECRET is not defined

[lucianobragaweb]

For me works only run:

php artisan jwt:secret

and after:

php artisan clear-compiled && php artisan optimize

Works Fine!!
Thanks!!

[deniwerikmartins]

For me works only run:

php artisan jwt:secret

and after:

php artisan clear-compiled && php artisan optimize

Works Fine!!
Thanks!!

THIS WORKS!!!

[rafaelxavierborges]

composer update
php artisan vendor:publish
php artisan jwt:secret

Verify if JWT_SECRET is defined in your ENV file or even in config/jwt.php

php artisan config:clear
php artisan cache:clear
php artisan clear-compiled && php artisan optimize
composer dumpautoload

This worked fine for me.
=)

[soamazyng]

php artisan jwt:secret. I clear laravel cache using php artisan clear-compiled && php artisan optimize

[mohanlar96]

are you already run command php artisan jwt:secret to generate jwt secret key in your heroku?

Thank you :) working good

[ajaymarathe]

are you already run command php artisan jwt:secret to generate jwt secret key in your heroku?

This helps.. thanks :)

[Nataanthoni]

Simply add the below JWT_SECRET from your local .env file at the bottom of your remote .env file

Something like;
JWT_SECRET=roCZauuldMpw5i4039393939393372y98bEWumqd9ls7Uk8DEpr0gIZ6WIWB

Hope this helps :)

[marcos1262]

For me, using Heroku,
heroku run php artisan jwt:secret
was not working, but
heroku config:set JWT_SECRET=<your generated key>
worked.
And then clear cache.
