UNSOLVED MMM-PublicTransportHafas brings up ERRORs `fetchDepartures`

[binderth]

Installed and configured MMM-PublicTransportHafas and it shows the same infos I get with the Bahn-App or bahn.de. But on startup I regularly receive those ERRORs - can I avoid those as I don’t know if there’s some side effects attached to them?

sometimes there’s only 3 ERRORs, sometimes there’s more. They don’t show after the appear on (re)start.

				showOnlyLineNumbers: false					// Display only the line number instead of the complete name, i. e. "11" instead of "STR 11"
			}
		},

PS: stationID is correct, just marked for privacy

I got the same issue. But there are other errors as well since I installed PublicTransportHafas.

Is there any clue why this happens?

Best,
