I was getting this error too.

Looks like uncommenting this if statement fixes it.

The upcycler seems to work fine now for me. It seems to always be "active" though. As soon as you place it it starts "processing" nothing, but if you feed it items it takes it and eventually spits out the upcycled item.

Edit: I forgot to mention, I am running Factorio 2.0.24
