Exception due to closure in config when using artisan config:cache

[developerdino]

When caching the laravel config via artisan cache:config command I am getting errors due to laravel not supporting closures in the config cache.

PHP Fatal error:  Call to undefined method Closure::__set_state() in /home/vagrant/Code/my-api/bootstrap/cache/config.php on line 264
PHP Stack trace:
PHP   1. {main}() /home/vagrant/Code/my-api/artisan:0

config/jwt.php is the standard one in the documentation and fails on the lines https://github.com/tymondesigns/jwt-auth/blob/laravel-5/src/config/config.php#L149-L151 and https://github.com/tymondesigns/jwt-auth/blob/laravel-5/src/config/config.php#L162-L164

Cached config for jwt section:

266                    'storage' =>
267                        Closure::__set_state(array(
268                        )),
269                ),
270        ),

Using Laravel 5.1 - not sure if the same issue exists in Laravel 5.0.

It seems that this is an issue with other projects that use this technique for the config - efficiently/authority-controller#27

Is there an updated config that you suggest which doesn't use closures in the config?

Thanks

If you are not customizing the providers then you can simply pass a class path as a string and laravel's iOC will build the instance

[tymondesigns]

Going to look at adding closure serialization via SuperClosure or similar

[tymondesigns]

Switching to using string namespace paths for now. I think this may be resolved on the Laravel side.

I'm having this error. Ways to fix ?

[developerdino]

@hilnius you just need to replace your config/jwt.php with what is in the develop branch here https://github.com/tymondesigns/jwt-auth/blob/develop/config/config.php#L113-L148 and that fixes the issue.

Edit: you'll need to export the jwt config first if you habvn't done it yet using php artisan vendor:publish

[jadjoubran]

Graham mentioned that they will not fix it
laravel/framework#9625

[hilnius]

@mofodojodino 's answer actually fixed it.
