curl request to OIC not working

Content

Hello guys,

I have a custom process that makes a curl request to OIC. I am using POST method. I get a response of 1 but the request never gets to OIC (when can check it on the OIC log).

When I use GET method or call it from a javascript add-in and even when I test it on postman, the request works - we can see it on the OIC log and we receive the expected response. 

My OSvC version is 19B. 

Is there any configuration I should enable to use this? 

I have attached part of my code bellow (only had to hide part of our url).
