I just install ‘mcamara/laravel-localization’ after install follow to steps and add

Route::group( [     'prefix' => LaravelLocalization::setLocale(),     'middleware' => [ 'localeSessionRedirect', 'localizationRedirect', 'localeViewPath' ] ], function(){ //... }); 

to my route. After that, I encounter

Mcamara\LaravelLocalization\Exceptions\SupportedLocalesNotDefined Supported locales must be defined. 

I guess it is not read to the config file for Supported locales array. So don’t know how to fix it. I am using laravel 7.19.1. I need help.
