Adding new create action produces error in resource schema

I have two resources in the same domain, Container, Image and ImageCredentials. Container has a belongs_to relationship with Image, Image has a has_many relationship with Container and a belongs_to relationship with ImageCredentials, while this last one has a has_many relationship with it. Container has a create action (:create_with_nested), with the purpose of creating a new Image in case of a failed match or lookup. I'm fairly new to Ash, and I tried to add the same logic to Image if it cannot match or lookup a ImageCredentials by adding the following :create_with_nested action to Image:

create :create_with_nested do
  accept [:reference]

  argument :credentials, :map

  change manage_relationship(:credentials,
           on_no_match: :create,
           on_lookup: :relate,
           on_match: :ignore,
           use_identities: [:label]
         )
  end
end

create :create_with_nested do
  accept [:reference]

  argument :credentials, :map

  change manage_relationship(:credentials,
           on_no_match: :create,
           on_lookup: :relate,
           on_match: :ignore,
           use_identities: [:label]
         )
  end
end

and modifying Container's :create_with_nested to use it on a failed match: on_no_match: {:create, :create_with_nested}. In doing so, I come across a compile error that I don't really understand:

== Compilation error in file lib/edgehog_web/schema.ex ==
** (Absinthe.Schema.Error) Compilation failed:

This error is triggered only if the Container's :create_with_nested is present, but doesn't come up if I revert it to use the default create for Image. Am I doing something wrong? To me the relationship between Container and Image looks no different from the one between Image and ImageCredentials, so I don't see why manage_relationship/3 works for one but not the other

container.ex

image_credentials.ex

image.ex

Hm...this looks like a bug in AshGrapqhl 🤔 Could you work up a production and open an issue?

I should mention the project is using Ash v3.4.53 and AshGraphql v1.5.0 If that makes any difference I'll still try to work on a small reproduction
