could anyone help me with this problem?
while trying to use a ROP geometry output node, after generating a node this error comes up (Multiple work items list the same file as their expected output)
could someone tell me what could I do?

I am using Houdini 20.0.751. Same problem as you described.

This is expected behavior if multiple work items are trying to write data to a single file.

I have not watched this tutorial, but have studied the final scenes they work without this warning.

At what stage do you get this warning?
