Hello.

When I want to use the "perspective" tool, I get this error :

Traceback (most recent call last):
  File "/app/share/inkscape/extensions/perspective.py", line 136, in <module>
    Perspective().run()
  File "/app/share/inkscape/extensions/inkex/base.py", line 131, in run
    self.save_raw(self.effect())
  File "/app/share/inkscape/extensions/perspective.py", line 64, in effect
    bbox = obj.bounding_box(obj.getparent().composed_transform())
  File "/app/share/inkscape/extensions/inkex/elements/_base.py", line 165, in __getattr__
    raise AttributeError(f"Can't find attribute {self.typename}.{name}")
AttributeError: Can't find attribute SvgDocumentElement.composed_transform

 

To be precise, use Inkscape 1.1 on Fedora 34. I create a 5-node closed path, the a trapezium (4-nodes), then select the 1^st one, then the 2^nd one while pressing "Shift", then, in the menu, extensions→modify path→perspective.

Any idea ?

I got the same error and prefer the LPE over the extension:
