How to use Observer when deleting a model?

Question

Laravel

Hello. I use Laravel 5.8 and use Observer to interact with CRUD operations.
Creation, update works as it should. But I ran into a problem when deleting the model.
If the Observer has deleting or deleted methods, then when I try to delete the model, I get a ValidationException with the message The given data was invalid. And the errors of my request fall out, which is used when working with a form to create / edit a model.
If the above methods are overwritten, then the removal works correctly.
Where to dig? And why does the validator twitch when deleted?
UPD . I decided myself. Passed the request to the Observera constructor. This request twitches on all operations except deletion, which is why the exception was called. The question is closed.
