In Laravel, the framework provides robust authentication mechanisms out of the box, making it easier for developers to implement user authentication features. However, sometimes errors can occur during the authentication process, such as the one stating “App\Http\Controllers\Auth\LoginController::credentials() must be an instance of App\Http\Controllers\Auth\Request, instance of Illuminate\Http\Request”. This error message may seem cryptic at first, but it typically indicates a mismatch or conflict in the type of request object being used. In this blog post, we’ll delve into the causes of this error and discuss how to resolve it effectively.

Go to your Login Controller and add the below class.

use \Illuminate\Http\Request;
