Description

How can I have a generic JSON as an input

"params": {
    "varA": {
      "x": "2",
      "version": 4
    },
    "y":  [{
              "p": 228.0,
              "q": "abcd"
            }]
}

If I define y: List[Json] I get:

"msg": "JSON object must be str, bytes or bytearray",
HTTP/1.1" 422 Unprocessable Entity

or y: List[str] or y: str
HTTP/1.1" 400 Bad Request

Is it possible to have a generic JSON List as an input instead of having to define a hard-coded Pydantic BaseModel?

y: List[dict] or y: List[typing.Any]?
