Hello Community,

I am consuming set of APIs in my application. So far all the APIs worked and none of them was sending much information in body. Now there is another API that I need to consume which accepts three sets of information: Credentials, Parameters and Configurations.

When I run this API in postman it runs fine and I get proper response. Whereas with same body JSON when I run it in OutSystems the third set of information i.e. Configurations gets removed and I get 500 internal server changes. On generating the API trace I get below details. Please let me know if anyone has faced similar issue and how to resolve it.
