When I try to create a custom message with annotation argument. I get [Syntax Error]

Question

The createFormBuilder pass through a class Called RegisterValidation()

namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Validator\Constraints as Assert;


class RegisterValidation extends AbstractType
{

    /**
     * @var string
     * @Assert\NotBlank( message = 'Enter first name please.') //This parameter trows an error
     */
    public $firstName;

}

I'm learning annotations it looks very nice to use every day on a project. Unfortunately, this issue seems so specific that I cannot find any Symfony 4 documentation. I want to use a custom message to replace the default one.

The full error message is probably :

[Syntax Error] Expected PlainValue, got ''' at position ***

As explained, your message in annotation should be between doubles quotes " .

class RegisterValidation extends AbstractType
{

    /**
     * @var string
     * @Assert\NotBlank(message="Enter first name please.") // Message must be in double quotes
     */
    public $firstName;

}
