I'm trying to polygonize. But I'm getting an error message:
'NoneType' object has no attribute 'isMultipart' See log for more details
Basically what I'm trying to do is divide the city into blocks so I can assign a value to each block.
I'm not sure if I'm getting the error because of something about the lines or someting in the attribute table... Or something else.
Here's a closeup of what the street centerlines look like.
Maybe I need to clean up the lines or something, not sure. But anyway here's the error message I get when I run it.
