Argument 1 passed to ServiceProvider::registerCollections() must be of the type array, null given

[randhipp]

Hi, im on Laravel Framework 6.17.1 run into this :

Symfony\Component\Debug\Exception\FatalThrowableError : Argument 1 passed to Lanin\Laravel\ApiDebugger\ServiceProvider::registerCollections() must be of the type array, null given, called in E:\laragon-x86\www\w4c\vendor\lanin\laravel-api-debugger\src\ServiceProvider.php on line 26

any clue why this happen?
one can temporary fix by copy paste array from config to this ServiceProvider.php :

public function boot()
    {
        $configPath = __DIR__ . '/../config/api-debugger.php';
        $this->publishes([$configPath => config_path('api-debugger.php')]);
        $this->mergeConfigFrom($configPath, 'api-debugger');

        // Register collections only for debug environment.
        $config = $this->app['config'];
        if ($config['app.debug']) {
            $this->registerCollections([
                // Database queries.
                \Lanin\Laravel\ApiDebugger\Collections\QueriesCollection::class,

                // Show cache events.
                \Lanin\Laravel\ApiDebugger\Collections\CacheCollection::class,

                // Profile custom events.
                \Lanin\Laravel\ApiDebugger\Collections\ProfilingCollection::class,
            ]);
        }
    }
