Update Params in Nested Form with Union type

I have a code snippet that looks as follows:

def update_subform_field(root_form, subform_name, new_value) do
  AshPhoenix.Form.update_form(root_form, subform_name, fn sub_form ->
    AshPhoenix.Form.update_params(sub_form, fn current_params ->
      Map.put(current_params, :my_field, new_value)
    end, only_touched?: true)
  end)
end

def update_subform_field(root_form, subform_name, new_value) do
  AshPhoenix.Form.update_form(root_form, subform_name, fn sub_form ->
    AshPhoenix.Form.update_params(sub_form, fn current_params ->
      Map.put(current_params, :my_field, new_value)
    end, only_touched?: true)
  end)
end

The given values are

["A"]

["A"]

["A", "B"]

["A", "B"]

. Using

IO.inspect

IO.inspect

, I can see that the

Map.put

Map.put

call works properly. However, in the result of the

update_params

update_params

call, the

raw_params

raw_params

field is updated, but the

params

params

field is not.
Removing the

only_touched?: true

only_touched?: true

causes an error during form validation (see stacktrace in thread). To me this suggests that it is a validation error someway. The

my_field

my_field

attribute is defined as

attribute :my_field, :union,
  allow_nil?: true,
  public?: true,
  constraints: [
    types: [
      %{:string, %{type: :string}},
      %{:string_array, %{type: {:array, :string}}},
      # ...
    ]
  ],
  default: nil

attribute :my_field, :union,
  allow_nil?: true,
  public?: true,
  constraints: [
    types: [
      %{:string, %{type: :string}},
      %{:string_array, %{type: {:array, :string}}},
      # ...
    ]
  ],
  default: nil

which, admittedly, is slightly complicated.

Does anyone have a clue what might be going wrong here?
