foreach() argument must be of type array|object, null given

[philharmonie]

Installed the package as described and get

foreach() argument must be of type array|object, null given

for @laravelPWA.
It is related to this foreach loop.

What I noticed, is that after $ php artisan vendor:publish --provider="LaravelPWA\Providers\LaravelPWAServiceProvider" there is just the serviceworker.js but not the manifest.json. The file is in public and not as mentioned in the troubleshooting in the project root, but I'd say, that is correct.

After researching I fixed it by adding a default value for the config. I removed the custom key in the config.php because I thought, it is not needed.
