Troubleshooting the Undefined array key "table" Error in Laravel's Auth Facade

Laravel is a powerful PHP framework that makes web application development easier and more efficient. However, as with any technology, you may encounter bumps on the road as you learn. One common issue new Laravel developers face is the error: Undefined array key "table" when working with the Auth facade. In this guide, we will dissect this error and provide a comprehensive solution to help you move forward smoothly.
