hda_node = subnet.createDigitalAsset(

on_created_body = "hda_node = kwargs.get('node')"
on_created_body += "\nprint('hello', hda_node)"
hdadef = hda_node.type().definition()
# these two lines fail most of the time...
hdadef.addSection("OnCreated", on_created_body)
hdadef.setExtraFileOption("OnCreated" + "/IsPython", True)

When calling either of the lines hdadef.addSection or hdadef.setExtraFileOption, I get a popup warning
"The attempted operation failed. Failed to save updated definition."

How can I set the node definition section safely, without getting this error.

Thanks for any help

Hello this is Gulshan Negi
Well, there may be some reasons for this and I search about it on the Google, and I found that there are some common issues that you may want to check:

1. Permissions: Make sure that the user running the script has write access to the node definition file.
2. Definition locked: Sometimes, the node definition file may be locked by another user or process. Try closing the node in the Houdini interface, and then running the script again.
3. Incorrect path: Double-check that the path to the node definition file is correct. If the path is incorrect, Houdini may not be able to locate the file and save the changes.

I am sure any one of them can help you.
Thanks

Hey Braden. I ran your code as is (almost - just took out the install_path argument) and it ran fine and the extra section has been added to the hda. So, the code itself doesn't seem to be the problem..
