Hi everyone,
After upgrading to Houdini Version 18.5.696 from 18.5.672 for win64, I get the following Syntax Error every time I place a "Labs Niagara ROP" node and the node has also stopped rendering an output (refer attached image)

Error running event handler:
SyntaxError: ('invalid syntax', ('labs:: Driver/niagara_rop, PythonModule', 36, 28, ' print(message, file=sys.stderr)\n'))

I am using Version 2.1 of the Houdini-Niagara Plugin for UE4.26 on Windows 10.
Any suggestion will be greatly appreciated, since I am not being able to move to the current version of Houdini.

Hi again, I managed to resolve this problem with help from SideFX Support Team.

Solution is to upgrade to SideFX Labs Build 18.5.713, which is not yet a Production Build.

Where did you get that build from. I am having the same issue

Never mind I just did it inside Houdini. I am running 18.5.758 and it fixed the problem.
