LookupError when trying to use dash.ctx.triggered_id in a DjangoDash app

Dash Python

Hi folks!

When I try to use dash.ctx.triggered_id (in a callback) I’m getting this error:

Internal Server Error: /django_plotly_dash/app/Frontend/_dash-update-component

I’m getting a similar message when using dash.callback_context.triggered[0][‘prop_id’] as proposed here: Lookup Error When Using Context_Callback - #8 by bershika
Since this is a DjangoDash app I obviously have no app.run() call. Maybe I have to tell the DjangoDash class to somehow initialize something in addition to the normal stuff?

Any help is highly appreciated!
