Bug: Fails for nest list of non_null

[kirega]

Steps to reproduce

When a field has the following definitions, the library will through an error

field :test, :test do 
      arg(:ids, non_null(list_of(non_null(:id))), directives: [constraints: [format: "uuid"]])
end

Error

Invalid constraints for field/arg ids of type %Absinthe.Blueprint.TypeReference.NonNull{of_type: %Absinthe.Blueprint.TypeReference.List{of_type: %Absinthe.Blueprint.TypeReference.NonNull{of_type: :string, errors: []}, errors: []}, errors: []}: [:format]

Thank you for reporting this.

Constraints for elements of a list are not yet implemented:

absinthe_constraints/lib/absinthe_constraints/phase.ex

Line 62 in c56cddf

# TODO: We could also validate the items inside lists with other constraints.

Currently the only constraints the library supports for lists are about the list itself and not its items (min_length and max_length).

We would like to implement this eventually, and PRs are always welcome.
