@mdebeer the error you’re seeing is unrleated but JFYI I haven’t implemented AliasWithName yet. It’s still on my list. We had internal use cases to prioritize first. I’ll let you know when I get around to it.
If you want to work around the issue you’re seeing there, you’re seeing an issue with mismatched definitions from the generated op descriptors and the model import there. If you want to try to work through that you can, but then you’ll still need to add the definition for the AliasWithName as well.
