"Test it" tool for AI ask is prepopulated with erroneous request body

It appears that all of the AI ask endpoints descriptions on this page show the body as only requiring a query parameter. However, if you go to run a request via the "Test it" button on that page, the editor loads with the following request body prepopulated:

{
  "query": "",
  "previousQueries": [
    null
  ]
}

If you fill in your query and run it as-is, without editing the contents of the previousQueries array, you'll get the following 422 error response:

{
  "error": {
    "code": 422,
    "message": "body.previousQueries.0: expected a string"
  }
}

Editing the body to make previousQueries be an empty array, or deleting previousQueries entirely causes the request to succeed. Given that previousQueries is deprecated and appears to no longer be functional, I'd think it should be removed from the "Test it" tool.

Start with the AI ask endpoint documentation at the linked search reference page and inspect the request body used by its “Test it” tool. Remove the deprecated previousQueries value from the prepopulated body, then verify that a request containing only query succeeds without the 422 response.
