Unable to send a `Ash.Type.File` as argument to action using `AshPhoenix.Form`

When trying to send a Ash.Type.File struct as an argument to an update action, AshPhoenix.Form is failing on validation. Worth nothing that sending the file argument as :override_params in AshPhoenix.Form.submit does bypass this and work correctly, as does calling the action directly. AshAdmin also exhibits this behaviour. Am I doing something wrong or is this a bug? The action looks like this:

update :update_avatar do
  require_atomic? false
  accept []
  argument :avatar, Ash.Type.File, allow_nil?: true
  argument :filename, :string, allow_nil?: true

  change &handle_avatar/2 # actually saves the file and stores path to DB
end

update :update_avatar do
  require_atomic? false
  accept []
  argument :avatar, Ash.Type.File, allow_nil?: true
  argument :filename, :string, allow_nil?: true

  change &handle_avatar/2 # actually saves the file and stores path to DB
end

🤔 something is strange there for sure It seems like you're passing an individual file when a map of params is expected though

quartzOP•4mo ago

yeah it was working some time ago I remember, and like I said above, same problem happens in AshAdmin

ZachDaniel•4mo ago

🤔 interesting. Can you create a reproduction project and open an issue?
