Hey guys
I got stuck just 1 step ahead as you @chris.welch. My PR fixed the issue specifically on the Converters, but there are more places where the components are assuming there will be an ActiveDoc (e.g. the SyncReceiver).
I believe if you choose “do not convert” you will walk one step further. The thing is now you will need to convert things manually, that’s very possible and there are examples on the forum (Speckle nodes and Hops - #7 by vwb).
What is not possible, yet, is to disable the conversion on the SyncSender. Meaning you will stumble on the same exception if your workflow needs to send anything back to Speckle.
I had to drop working with this for a while, but intend to come back and contribute if more people are interested.
