Unknown error my user cause - no idea where it originates from.

Hi, every now and then the Anvil log shows the following error. Probably caused by the multiselect in a sub form.

ExternalError: [object Event] at app/anvil_extras/utils/_component_helpers.py, line 83 called from app/anvil_extras/utils/_component_helpers.py, line 52 called from app/anvil_extras/MultiSelectDropDown/__init__.py, line 40 AttributeError: 'jQuery' object has no attribute 'selectpicker' at app/anvil_extras/MultiSelectDropDown/__init__.py, line 42

I've never managed to cause the error myself. Any idea on what to do to narrow it down (I can't interact with the user who caused it...)? The error doesn't seem to do any harm. But it is nagging me that there is somewhere some problem.

Thanks - Arne
