Colang 2.0 multi_modal tutorial error

Running the multi_modal_demo_v2_x tutorial when trying to start the number guessing flow, play the number guessing game, it fails with this error if I run it as a server.

Does this demo require a special UI?

The server UI does not work with Colang 2.0. You can only test it through the nemoguardrails chat CLI. We'll try to fix for 0.10 as well.

Thanks, with the multi-modal gestures are there any interfaces that you're working with that support this with graphics or digital human interfaces?
