Extracting Method doesn't work

[DarkRedman]

I use the function Extract Method, I put the name of my function and press enter and I get that :

Traceback (most recent call last):
  File "/home/<username>/stats/gestion/tmpmmq31e", line 12, in <module>
    changes = ExtractMethod(myproject, ropy, 34, 37).get_changes('sum', similar=True)
  File "/usr/lib/python3.10/site-packages/rope/refactor/extract.py", line 83, in get_changes
    new_contents = _ExtractPerformer(info).extract()
