422 Unprocessable Entity when using do_service_async

[ahbe]

When using do_service_async to communicate a POST call to another service that requires a JSON data I always get a 422 Unpro cessable Entity error

data = {"image":"path_image_str"}

try:
    res = await eureka_client.do_service_async("app_name", "/api_path",method="POST",data=data,headers={"Authorization": 'Bearer ' + token})
except urllib.request.HTTPError as e:
    print(e) 

I've tried using json.dumps but it yield another error : res was used before being assigned

If json.dumps doesn't work, please check your server side logic. And please check whether your server side accept application/json data but not application/x-www-form-urlencoded
