ComboBox activated(int) does not get the index argument with PyQt5

I have a python script doig the following:

class MainWindow(QQuickView):
    def __init__(self):
        ...
        self.screen1usageCombo = self.findChild(QtCore.QObject, "combo_screen1_usage")
        self.screen1usageCombo.activated.connect(self.change_screen1_mode)
...
    @asyncSlot()
    async def change_screen1_mode(self, index):
        ...

It works perfectly with Pyside2, but with PyQt5 (both 5.13.2 and 5.14.1) the result is:

Traceback (most recent call last):
  File "/home/yann/.local/lib/python3.7/site-packages/asyncqt/__init__.py", line 644, in wrapper
    asyncio.ensure_future(fn(*args, **kwargs))
TypeError: change_screen1_mode() missing 1 required positional argument: 'index'
Aborted

Confirmed on my side as well!

I think you have to pass the type to the slot decorator, try this: @asyncSlot(object).
