i search about this method and i did not found it in all framewark
i search in github also i did not found it ??!
I couldn’t find as well. Possible it is a uncleaned code, and just don’t do anything?
Can you put any arbitrary, i.e., “do_nothing” string and see if it error?
nothing happen even I changed it to doc.run_method("do_nothing")
So the line can be removed, I guess.
Can you report as a PR to ERPNext?
