Unable to set minLength on property

[Invis1ble]

My form contains RepeatedType of PasswordType:

$builder
    ->add('plainPassword', RepeatedType::class, [
        'type' => PasswordType::class,
    ])
;

validation rules looks like this:

plainPassword:
    - NotBlank: ~
    - Length:
        min: 6
        max: 255

so ValidatorGuesser can't guess length and StringTransformer::addMinLength() doesn't add minLength.

I would suggest to look at attr.minlength option like in addMaxLength() method and, if it not exists, run default algorithm of guessing by validation rules.
