The option "extra_options" does not exist.

Hi
I'm now upgrading my Symfony 6.3 application to 6.4 and I've also updated symfony/ux-autocomplete to the 2.15.0 version.

Now each time I'm trying to use my autocomplete field I'm getting error:
An error has occurred resolving the options of the form "App\Form\Autocomplete\MemberSingleAutocompleteField": The option "extra_options" does not exist. Defined options are: "action", "allow_extra_fields", ....
I've noticed that this extra_options was introduced in #1322.

Should I stick to 2.14 version in order to use it with 6.4 Symfony?

The extra_options exists in 2.15.0, but it is available for form types extending from:

        return [
            ChoiceType::class,
            TextType::class,
        ];

What does your MemberSingleAutocompleteField descend from ?

I am getting the error, too.

An error has occurred resolving the options of the form "App\Form\KundendatenAutocompleteField": The option "extra_options" does not exist. Defined options are: "action",

The relevant parts of KundendatenAutocompleteField:

use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
...
class KundendatenAutocompleteField extends ChoiceType
...

Using Symfony\Component\Form\AbstractType or Symfony\Component\Form\Extension\Core\Type\TextType results in the same error.

For autocomplete since 2.13 you need
public function getParent(): string { return BaseEntityAutocompleteType::class; }

instead of
public function getParent(): string { return ParentEntityAutocompleteType::class; }

https://symfony.com/bundles/ux-autocomplete/current/index.html#usage-in-a-form-with-ajax
at least that was my issue

@bdujon - brilliant! 😄 It is working now. Thank you!

I wonder that maybe it would be worth to add it as a comment in symfony console make:autocomplete-field?
Autogenerated class uses ParentEntityAutocompleteType::class; which is fine when you are not using Ajax but is not otherwise. Error message was missleading here (at least for me).

For example:

Customize your new field class, then add it to a form:
 
     $builder
         // ...
         ->add('user', Foo::class)
     ;

Add somethig like: Change getParent() acordingly if using with Ajax.
