Using Ask Assistant with Basic ChatGPT Template ?

Hi Everyone;

Via the OpenAI Playground I have an assistant which have a good VectorDB and I would like to use it via TypeBot for a client.

When

1. I replace Create Chat Completion by Ask Assistant
2. then choose my Assistant ID
3. then Test

TypeBot systematically give an error message: that the Message is empty

Q: So how could I connect the collected User Message from the User Input to ChatGPT Reply ?
