[BUG] 422 using a dict body with 0.27.0

The following endpoint was running fine with 0.26.0 and Python 3.6.5:

@app.patch(“/ps/user”) async def patch_user(user_dict: dict, add: List[str] = Query(None)) -> dict: …

but with upgrading to 0.27.0 I got the following 422 error:

{
    "detail": [
        {
            "loc": [
                "query",
                "user_dict"
            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
}

I can’t find and according change in the last commits so I assume this is a bug?

Thanks, Daniel

Yep, it’s an old design decision by Requests 🤷😅
