I've added an avatar image to my User class. When I wanted to render my edit form, I got this error
Serialization of 'Symfony\Component\HttpFoundation\File\File' is not allowed
I tried to solve the problem by implementing \Serializable in my User class according to Symfony Official Documentation. But when I implemented that,It redirected to login page and the Authentication turned to anon. and by logging in again, it redirected to login page again and stay anon. too.
I should mention that I have set some Authorizations. It will redirect you to the log in page if you are "anon." and want to access some protected routes.
Here is my UserEntity, User.php:

Fileinstance cannot be serialized. Probably, yourUserobject should not contain an instance ofFile? – TelesisFiletype instead of the file name(string). Please check this out: symfony.com/doc/current/controller/upload_file.html – ColdheartedFileinto your form causes an error, then don't do it. And if addingSerializableto the entity class solves that error, but causes another, you should adjust your question – TelesisUserentity. Also I need to put that file into my form, otherwise, it renders some other errors which want me to put theFilein. Anyway, thanks for helping. – ColdheartedUserentities where a login does not work properly. Probably, #8455837 could help? – Telesis
