Yeah, even the BakeHirestoLowres example from the docs is broken and displays the same error. The old bake texture node imports baketextureutil as a pre & post-render script which might be deprecated. I'd suggest editing your HDAs and replacing the old bake texture ROPs with the new one.
That being said, in 15.5 I'm having a terribly hard time finding out how to transfer surface normals from a hires to a lowres object. I guess you need a material assigned to the highres object to see at least a neutral normal map, but that is about how far I got…
Been trying to use it as well, seems like they didnt connect something correctly, writing out just N from the object gives us a world space normal map, (which even when i try to convert doesnt give me a proper result).
when i say just writing out N , I mean just bind exporting N from the global position root. strangely, the Tangent Normals gives me a flat .5 .5 1.0 color space but nothing else, no details. Id submit a bug report
Thanks for following up. Was pulling out my hair over this - looks like a bug after all.
