How to make symfony validation not validate a field if it is null?

Question

symfony

entity:

/**
     * @ORM\Column(type="string", nullable=true)
     * @Assert\Image(
     *     mimeTypes={ "image/jpeg", "image/png", "image/gif" },
     *     minWidth=200,
     *     minHeight=200,
     *     maxHeight=4000,
     *     maxWidth=4000,
     *     detectCorrupted=true,
     *     maxSize="8M",
     *     maxRatio=3,
     *     minRatio=0.25
     * )
     */
    protected $passport = null;

If the user has not uploaded, then he is shown an error, but this field is not required.
How to fix it?

Answer 1

Try to set the attribute "required" = false in the form

Answer 2

@Assert\Null()
