I keep getting a 422 error on my upload-csv-file request for some reason. I’m not sure why. I’m trying to upload a customer uploaded csv file to s3:

here is my frontend:

            if (csvFile) {
                let fd = new FormData();
                fd.append("file", csvFile);
                await post('/candidate/upload-csv-file', fd, {
                    headers: {
                        'Content-Type': 'multipart/form-data'
                    }
                });
            }

here is the backend:

@router.post("/candidate/upload-csv-file")
async def create_upload_file(file: UploadFile = File(...)):
    with tempfile.TemporaryDirectory() as temp_dir:
        with open(f"{temp_dir}/{file.filename}", "wb") as tmp:
            content = await file.read()  # async read
            tmp.write(content)

            timestamp = int(time.time())
            csv_imports_datastore = Datastore("csv_imports_cloud", db="heymilo_platform")
            object_name = f"csv/entry_{'posting_id'}_{timestamp}.csv"
            s3_url = svc_cloud_upload.upload_file(tmp.name, object_name=object_name,
                                                  content_type="text/csv")
            if not s3_url:
                raise Exception("Failed to upload file to S3")

            csv_metadata = {
                    "posting_id": 'posting_id',
                    "s3_url": s3_url,
                    "timestamp": datetime.now(),
                    "timestamp_unix": time.time()
                }
        
            csv_imports_datastore.collection.insert_one(csv_metadata)
            
            return {
                "filename": s3_url
            }

Here is the error:

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

I’m trying to isolate if this is a backend/frontend issue, or something else. The payload is empty in the request:
empty payload

I tried on postman but get the same 422 error.
