It seems impossible to get an inline chat prompt working. It's not possible from the UI and the api returns an invalid template configuration error without saying why. The chat configuration I send to the API is one I got from bedrock prompt management, which uses the exact same structure plus a few more fields - will attach here soon

Get prompt output:

% aws bedrock-agent get-prompt --prompt-identifier <prompt-id>
