. dot not possible in url param

Hello, I just wanted to install a cool function for a sales department. The URL query parameters should be automatically inserted into the form:

    protected function fillForm(): void
    {
        parent::fillForm();
        $this->form->fill(request()->query());
    }

    protected function fillForm(): void
    {
        parent::fillForm();
        $this->form->fill(request()->query());
    }

But as soon as there is a dot in the URL, for example in the e-mail address, I get a 404

/create?first_name=John&last_name=Doe&email=johndoe%40example.com

/create?first_name=John&last_name=Doe&email=johndoe%40example.com
