Events do not load

[isntfunny]

The request to load the calendar entries tells me this error:

{"error":true,"message":"Pflichtparameter fehlen: start"} when requesting s/willkommens-space/calendar/view/load-ajax?start=2023-07-31&end=2023-08-07.

It's a completely new installation. Only added one calender entry, did not install the example data.

The same happens for the global calendar:
calendar/global/load-ajax?start=2023-07-31&end=2023-09-11: {"error":true,"message":"Pflichtparameter fehlen: start"}

@isntfunny Could you please tell what version you use?
It would be good if you can provide more info with screenshots of the error and options of the calendar entry.

I have tested with versions Calendar 1.5.3 and HumHub 1.14.4 with fresh install without example data.

Also I tried to pass an empty value for the param start, it just returns [].
I have reviewed a code of the module calendar and I cannot find a code which may returns the array with keys error and message.

Thanks.
