Upload files in Postman with FastAPI

I have a promblem with Postman and FasrtAPI. Wrote thin code for FastAPI. First is for single image, second for mulriple. In FastAPI Swaager it all works fine, but my POST requests with files or images it fails, i got this

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

And here is the code
