Question

Why Azure functions http trigger post api response is blank but the success code is 200 ok ? It works locally with the response message

Answer 1

Hi Avneet,

The return type of the Azure function has to be a valid JObject. (Keep in mind that JArray is not a JObject.) Any return type other than JObject fails and raises the user error Response Content is not a valid JObject.

Feel free to reach out to me if you have any questions or concerns.

@Avneet Singh The default return value for an HTTP-triggered function is:

• HTTP 204 No Content with an empty body in Functions 2.x and higher
• HTTP 200 OK with an empty body in Functions 1.x

To modify the HTTP response, you need to configure an output binding.
