Possibly false alarm when exporting vector path from Figma

.fig project attached. One should only export "iconMenu" inside Frame 1 to see the problem. The other 2 images are the export settings.

The problem is that bridge for Figma complains about "iconMenu has unsupported fills properties". Not sure what that means since I see no fill being applied. And being imported into QDS, the result .ui.qml looks fine to me too. So maybe a false alarm (not sure though).
