In the thread
the problem was that no routing profile was selected.
I reproduced such a bug by taking an valid route url
and replaced “&weighting=fastest&” by “&weighting=&” in the url
Then I get also an LM Profile error (red box, clicking creates thread in Kurviger forum).
It might be helpful to include url in thread text created by click on error box, but route information might be privacy …
But catching unset / illegal query paremeters and setting them to default values might help.
In the error example above I am trapped in that error due to missing profile:
Even deleting route and overlay does not help - after setting start and destination an LM Profile error appears.
Remark: Of course tapping on a profile button helps.
