Urgent: Azure function returns response in postman but not in azure portal or Data Factory

Question

Hi,

I deployed a POST http trigger function and deployed to portal. When I take the function url and test from postman returns the expected result. But when I run from Azure portal function app by clicking 'Code + Test' option is showing 200 OK but the response coming as empty. Please let me know if I missing anything.

Thanks,
Jeevi

Please make sure that the return type is valid Jobject when running from ADF pipeline. 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.
