How to Stop the Action GPT from encoding the body of an API request in made up json, rather than straight text

Hi,

I have an openAPI config that (to the best of my knowledge specifies that the body content is to be sent as text.

snippet:

’ ```
post:

  requestBody:
  
    required: true
    content:
      text/plain:
        schema:
          type: string
despite my best effort, the action API insists on encoding the body as JSON

example API call:

{
“domain”: “xxxxxx”,
“method”: “post”,
“path”: "xxxxx,
“operation”: “executeQuery”,
“operation_hash”: “xxxxxx”,
“is_consequential”: true,
“params”: {
“response”: “search publications return year”
}
}


note that the encoding "response" is not present in the spec. It seems that the Action API makes this up...  Ofcourse, the api responds that it does not recognise the "response" keywork.
