add_path not found centerlines with Trim Iterations set

[dorinoltean]

I have qgis 3.18.3 on one computer where centerlines works fine. And qgis 3.20.0 on another computer where i get 'Graph' object has no attribute 'add_path'

On computer qgis 3.18.3 i have networkx==2.2 On computer qgis 3.20.0 i have networkx==2.5.1 -

@dorinoltean it would appear that Networkx have updated the API slighlty but I believe the issue is now solved.

Please reinstall the plugin and let me know.
