This is what worked for me:

[rossjcooper]

If you get this error in your CI tools when running tests be sure to set JWT_SECRET to something in phpunit.xml

 <server name="JWT_SECRET" value="..."/>

I came across this error when I deployed my application after testing and everything else worked well on the local server.

I noticed the following;

• It's possible that you are getting this error when you uploaded the applications before implementing the JWT and re-uploaded directly via the Cpanel upload without reuploading the .env file.

  • if this is the case, the simplest way to solve this is my merely adding the JWT: key in your .env file (at the bottom) eg

JWT_SECRET=roCZauuldMpw5i4039393939393372y98bEWumqd9ls7Uk8DEpr0gIZ6WIWB

Hope this helps :)

[viniciusmelocodes]

This is what worked for me:
php artisan jwt:secret
php artisan config:clear
php artisan config:cache
sudo chmod 777 -Rf storage/

[mhlanga-joseph]

@Nataanthoni answer worked for me. Unfortunately, I had not set a JWT_SECRET in my .env. My bad!

[blessingk]

This is what worked for me:

php artisan jwt:secret
php artisan config:clear
php artisan config:cache

[gentritabazi01]

Lumen does not have config:clear or config:cache artisan command.

This error is still present in Lumen.

Estaba probando en heroku y me funcionó:

Obtener el secret key

heroku run bash
php artisan jwt:secret
php artisan config:clear
php artisan config:cache

Luego agregarla como variable (fuera de heroku bash)

heroku config:add JWT_SECRET={your jwt secret key}
