Symfony6, EasyAdmin4, problem while saving a new item in database from the EasyAdmin Interface

Question

I can't add a new Item via my EasyAdmin4 (with Symfony 6).. I fill the fields, click on create to add it in DB.. but instead I got this:

HTTP 500 Internal Server Error: RouteNotFoundException

Unable to generate a URL for the named route "app_login" as such route does not exist.

in C:...\vendor\symfony\routing\Generator\CompiledUrlGenerator.php (line 50)

and by inspecting the page, I got this:

Uncaught TypeError: Sfjs.createFilters is not a function at HTMLDocument....

THE ERROR CAPTURE

Thanks a lot
