Answer by totymedli for Class App\Http\Controllers\ResetPasswordController does not exist

I got this error because the class's namespace declaration didn't match the path of the file. It was:

namespace App\Http\Controllers\Api\Auth;

While the file path was:

App\Http\Controllers\Auth\ResetPasswordController.php;

The Auth folder wasn't inside the Api folder so I either had to move the folder to there or change the namespace declaration to:

namespace App\Http\Controllers\Auth;
