The problem

map.py has an off-by-one error when rendering dashed lines that end up causing a divide by zero:

client.py/deebot_client/map.py

Line 505 in ebfae31

start = position / length

. I guess this is just a rare case when somebody's map specifically has two points to be rendered that are on top of each other.

When length is 0, it'll still perform the loop and crash.

Updated it to while position < length: locally and it now works perfectly on my map.

yep cool will do, just wanted to double check first in case you might already have a fix, or if there's something else about this code that i'm not aware of 🙂
