anyone fimiliar with this warning: unable to connect cryptomatte() to MtoaAovWriteColor(input) - types are not compatible (CLOSURE to RGBA)

When rendering cryptomattes in Maya with Arnold on deadline renderfarm the cryptomattes are empty. I see the AOV's but there is no information in there. The render log is giving me this warning: unable to connect cryptomatte() to MtoaAovWriteColor(input) - types are not compatible (CLOSURE to RGBA).

Not sure what to do with this. When I render local the AOV's render fine.

There are no errors or warnings loading the plugins:

cryptomatte.dll: cryptomatte uses Arnold 5.0.1.0

cryptomatte.dll: cryptomatte_filter uses Arnold 5.0.1.0

cryptomatte.dll: cryptomatte_manifest_driver uses Arnold 5.0.1.0

Somehow the cryptomatte shader is connected MtoaAovWriteColor, so you get that warning (which is expected in that situation). I'm guessing you've got different versions locally and on the render farm. It's impossible to say exactly without seeing a scene file or ass, and detailed logs from both machines.

Thanks! I see there is a difference in MtoA and Arnold Core versions.
