Target [Illuminate\Contracts\Auth\Access\Gate] is not instantiable

I'm upgrading Laravel from 5.2 to 5.3

I followed the steps mentioned here: https://laravel.com/docs/5.3/upgrade#upgrade-5.3.0

When I tried to to do composer update I kept getting:

[2021-04-12 06:15:52] build.ERROR: exception 'Illuminate\Contracts\Container\BindingResolutionException' with message 'Target [Illuminate\Contracts\Auth\Access\Gate] is not instantiable.' in XXXXXXXXXXXX/admin/vendor/laravel/framework/src/Illuminate/Container/Container.php:763

#8 /Users/ahmad/Projects/admin/app/Providers/AuthServiceProvider.php(26): Illuminate\Foundation\Support\Providers\AuthServiceProvider->registerPolicies()
#9 [internal function]: XXXXXX\Providers\AuthServiceProvider->boot()

I added the Gate to my providers array, and tried clearing the bootstrap cache folder and delete the vendor, and reinstall everything in the composer.json

Any advises?
