Text_box pressed_enter

I’m trying to tie an event (pressing enter) to calling an existing function. I can get the following to work when editing and running via the Anvil.Works platform, but when I take it offline and run it via the open source Anvil Server I get nothing when the Enter key is pressed within the stated text box. Do I need to update something else other than the Client Code for this binding ("…pressed_enter") to be recognized using the open source Anvil Server?

  #TIES ENTER BUTTON PRESS TO CALLING SEARCH FUNCTION:
  def bqs_to_find_text_box_pressed_enter(self, **event_args):
    """This method is called when the user presses Enter in the bqs_to_find_text_box"""
    print("He he, said the Pillsbury Dough Boy!")
    self.find_bqs_button_click()
    pass
