Error: object of type 'NoneType' has no len()

Hi. I ran into this error when trying to use the LRS plugin. I am stumped on what the issue could be. Maybe something with my data structure.

An error has occurred while executing Python code: 

TypeError: object of type 'NoneType' has no len() 
Traceback (most recent call last):

It seems that lines are of type which is not supported by plugin. Supported are LineString, LineString25D, MultiLineString, MultiLineString25D. What types are your lines? Other types were probably added in QGIS after the plugin was written.

Can you test also with QGIS 3 and plugin 1.0.2?

Closing because of missing feedback.

Yeah, sorry, got swamped with other work.
