Symfony/Form: Too few arguments to function DoctrineType::__construct()

I've got a weird error. I implemented the Form component in my own system. There I created a FormType where I use the EntityType for a field. Everytime i wanna create the form with the formBuilder it throws the following error:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function 
Symfony\Bridge\Doctrine\Form\Type\DoctrineType::__construct(), 0 passed in 
vendor/symfony/form/FormRegistry.php on line 92 and exactly 1 expected in 
vendor/symfony/doctrine-bridge/Form/Type/DoctrineType.php:102

Does anyone here has an idea why this is happening?

I had exactly the same issue. And found a solution.

It is indeed possible to use EntityType fields outside your project (e.g. in a bundle!)

Here is the solution:

1. Create an EntityType field class inside your bundle

(e.g. in src/Form/Builder/Type/EntityType.php)
Behind the scene, this class will inherit doctrines DoctrineType which (to this day) has a __construct() that requires a RegistryManager object parameter!

There lies your problem - the integrated bundle does not automatically wire the inherited constructors parameters, so you have to do this manually..

2. Add the same constructor from DoctrineType in your EntityType-class:
namespace MyCorp\FormsBundle\Form\Type;

use Doctrine\Persistence\ManagerRegistry;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;

class EntityType extends EntityType
{
    public function __construct(ManagerRegistry $registry)
    {
        parent::__construct($registry);
    }
}
3. Manually wire the ManagerRegistry object in your bundle's services.yaml
services:
    MyCorp\FormsBundle\Form\Type\FormEntityType:
        arguments:
            $registry: '@doctrine'

Now you can implement and inherit EntityType from your bundle within any project. Works perfectly!

If it does not work, your bundle's services.yaml may not being loaded correctly! Consider recent updates to symfony 6.2 having a new internal API for DependencyInjections, being available if your bundle main class inherits from AbstractBundle. You then, do not need a spearate BundleExtension class anymore, to ship your yaml configuration files.

In your bundle main class add this:

namespace MyCorp\FormsBundle;

class MyCorpFormsBundle extends AbstractBundle
{
    public function loadExtension(array $config, ContainerConfigurator $container, ContainerBuilder $builder): void
    {
        $container->import('../config/services.yaml');
    }
}

Your form might not be registered properly in the services.yml?

services:
    Namespace\Type\YourType:
        autowire: true
        tags:
            - { name: form.type }

You can also get this exact same error when using EntityType::class while you are actually using Doctrine's MongoDB ODM instead of their EntityManager

Solution for MongoDB is to use DocumentType::class instead of EntityType::class

Just add your form class inside services.yml. this method worked for me

[bundle_name].form.[class_name]:
   class: [bundle_name]\Form\Type\[class_name]
   arguments: ["@doctrine.orm.entity_manager"]
   tags:
     - { name: form.type }

careful with indention tho, cause yml requires proper indention.

I finally found the answer to my problem: It's NOT possible to use the EntityType class out of the SymfonyFramework context.

The reason is, that the EntityType::class needs multiple components to get resolved by the FormBuilder of Symfony. Of course you need Doctrine and the doctrine-bridge for Symfony. But for resolving the final entity from the EntityType::class, the DoctrineType:class needs a ManagerRegistry::class to be passed. With the ManagerRegistry the Doctrine connection can be resolved from the Symfony application.

So one possibility is to pass the entity manager or the already resolved entities with the config to the FormType and create a field with the ChoiceType::class type.

I hope this is helpful for some of you...

If you don't use Symfony Framework, enable autoconfigure and autowire in your services.yaml. Example :

App\Form\:
    resource: '../src/Form'
    autowire: true
    autoconfigure: true
