[Symfony] "FormType too few arguments passed 0, 1 argument needed" fix

It can be not only FormType, also can be any your custom form type. 

It can be when you moved your form into new namespace/bundle, but did not registered services in it. 

1. don't forget that your form should extend Symfony\Component\Form\AbstractType;
2. add new bundle namespace in composer.json
3. Create bundle extension file in ./DependencyInjection/FooExtenstion like this https://symfony.com/doc/current/bundles/extension.html
4. add this into your bundle services.yaml:

services:

    # default configuration for services in *this* file

    _defaults:

        autowire: true      # Automatically injects dependencies in your services.

        autoconfigure: true

    FooBundle\:

        resource: '../src/'

        exclude:

            - '../src/DependencyInjection/'

            - '../src/Entity/'

            - '../src/Kernel.php'

            - '../src/Tests/'

        5. run php bin/console cache:clear
