Denoiser not working when VrayEnhancerData element is present

When I try to denoise a render that has a VrayEnhancerData render element, I am getting the error:
error: [DenoiserApp::readMultiChannel] 0: Error the image file is incomplete, the data of channel "VRay Enhancer" is missing

The renders complete normally and I get the error when trying to denoise VRIMG and EXR files.

Any ideas?

Does this happen in 3ds Max or only when using the vdenoise.exe tool?

I do all our denoising on the command line using vdenoise.exe.
When I tried in 3ds max just now, the effect result channel just goes pink, but no errors are reported in the log.

We’ve logged the vdenoise issue (internal tracker ID: VMAX-15166).

What do you mean goes pink? Using both denoiser and enhancer in 3ds Max seems to work fine on my end.

Hopefully there will be a fix for this soon.

I can’t seem to replicate the pink effectsResult channel today, but if it comes up again I will report back.
