Script @php artisan package:discover handling the post-autoload-dump event returned with error code 1

[yashweb3]

composer require benwilkins/laravel-fcm-notification:dev-master
After running this command it will crash my project

After that composer dump-autoload is also stopped working.

FYI: This is run in Xampp, Laravel version is 5.6, PHP Version 7.1.18

Let me know if any solution for this. because it will crash my whole project. :(

Thanks

Getting the same error as well upon updating and found out that it is caused by this package. Removing this packaged fixed it but obviously, I need this package to work.

This only happen with version 3.0.1 (673adf7) because of PR #40 . For Laravel 5.6, you can only use version up to 3.0.0.
