I tried to use the hazmat-routing-option.
Sadly it seems like it isn’t working.
I tried a few water-protection-areas. All of them seem not to be regarded while routing with hazmat=true.
Following one example:
the calculated route with openrouteservice while hazmat is true
If you turn hazmat on or off it is the same route directly through the water-protection-area.
May you help. Or can explain why I am getting this error?
