[Qgis-user] QGIS2web crash

[Stephen Sacks]

QGIS2web problem.
My map has two layers (trees and shrubs).  If both layers use a single 
svg marker everything looks as it should, both on my desktop and when I 
export to the web (Leaflet).  But if one layer (shrubs) uses 
categorized  svg markers then qgis2web crashes when I click Export (see 
attached error message). The crash occurs even if all six categories use 
the same svg file (which is the same svg which works smoothly in the 
single marker, i.e., not-categorized, case). The error message says 
can't find 'chosen/ShrubPoss1_green.svg' , which is a reference to a 
folder and file which I had used earlier but don't use now.  I recreated 
both the folder and the file just so they can satisfy some software bug 
that failed to clear some buffer, but that does solve my problem.
I'm using QGIS2web(version 3.29.0) and running QGIS v3.40.10 Bratislava 
on Windows 11.
Any advice would be most welcome.  Thanks in advance for your time.
Steve
