Also getting this error recently. I have extra, magic and interfaces defined as arrays in the ide-helper config file. Still getting ErrorException : array_merge(): Expected parameter 2 to be an array, null given in vendor/barryvdh/laravel-ide-helper/src/Generator.php:53 ($this->extra = array_merge($this->extra, $this->config->get('ide-helper.extra'));)

Tried clearing all the caches etc, but no help.

I had the same error. This is how I solved it.

php artisan vendor:publish --provider="Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider" --tag=config

php artisan config:cache

That's it

Your config was cached, you need to clear it:

php artisan config:clear

Configs usually should only be cached in production.

[acidjazz]

config:clear did it for me, why don't we throw this command into the generate artisan?

$this->call('config:clear');

[netpok]

I would not expect a helper library to change the application state. In my opinion if someone decides to cache the config he/she should be the one who clears those cached values.

Supporting the last comment.

Also: ide-helper is meant to run in dev only and dev is not meant to be cached

[mfn]

@barryvdh config caching in dev produces this problems and it's generally bad practice to do this, I vote for closing this issue :}

(the readme doesn't mention this, I made myself a note to follow-up on this, but the issue isn't required for this)
