Laravel: Undefined index: App\Models\User

Undefined index: App\Models\User

Issue

This cryptic message often appears when one of your application's models can not be initialized.

Solution

If the model referenced in the error message does not exist, correcting the model reference to resolve the issue. If it does, check the referenced model for any initialization methods and ensure the method includes a call to its parent. For example, the boot method should call parent::boot().
