filter plugin with enum fields leave unresovled reference in compiled schema php

[MasonD]

class ClassWithEnum extends DataObject {
  public static $db = [ 'EnumField' => "Enum('OptionOne,OptionTwo','OptionOne')" ];
}

ClassWithEnum:
  fields:
    enumField: true
  operations:
    read: true

The compiled php code will contain a reference to Types::QueryFilterEnumFieldEnumComparator(), which does not exist.

Just to clarify, does this actually cause any errors or unexpected behaviour? If so, can you please specify exactly what happens?

[MasonD]

Yes, when a relevant operation is called, a reference error occurs. The underlying problem seems to be that the filter plugin that is enabled by default on read uses that type in the type for the filter input but doesn't create it.

I seem to have run into this issue as well (framework 4.10.12, graphql 4.0.1). The comparator is just never created for Enums in my DataObject.

Is there any news or maybe a solution?

Workaround posted by @Martimiz on the public slack:

For anyone who's interested: creating the exact same Enum in the enums section of the GraphQL config, and then adding that Enum as a type to the Model field acts as an interim solution.

Downgrading impact to medium as there is a workaround.
