API call from Shortcuts on Mac to Flowise produces unwanted metadata wrapper

[ahasibrm]

Within the Flowise canvas, if I create a conversational retrieval chain and ask it a simple question like

Why did Jack and Jill go up the hill?

I get a simple answer:

Jack and Jill went up the hill to fetch a pail of water.

Using my Mac, I want to create a Shortcut to do the same via an API call:

The result includes a wrapper that I don't want:

{"chatId":"d6e3de8e-b40f-477a-8696-f1e85ec0f5d4","chatMessageId":"8ecab197-adbe-47ee-a184-7184c7f2ed3c","question”:”why did Jack and Jill go up a hill?","text”:”Jack and Jill went up a hill to fetch a pail of water"}

How do I get the result without the wrapper?
