Hello
I am getting the below exception sometimes. Module already exist.

an exception was raised:
         ** (ArgumentError) send_update failed (module ... is not available)
 (phoenix_live_view 0.16.1) lib/phoenix_live_view/channel.ex:237: Phoenix.LiveView.Channel.handle_info/2

Does this happen in production, or in development? Is the rest of your code doing anything unusual with module loading? Because the error message demonstrates the module does NOT exist, at least sometimes:

github.com

phoenixframework/phoenix_live_view/blob/677667d0df0381c5e658d215996ebc311c9bf796/lib/phoenix_live_view/channel.ex#L231-L238


      
          if function_exported?(module, :__info__, 1) do
            # Only a warning, because there can be race conditions where a component is removed before a `send_update` happens.
            Logger.debug(
              "send_update failed because component #{inspect(module)} with ID #{inspect(id)} does not exist or it has been removed"
            )
          else
            raise ArgumentError, "send_update failed (module #{inspect(module)} is not available)"
          end

I see this in my local. Sometimes some tests fail with this error. When I rerun the test that error vanishes. I have not seen this error in production yet.
