Asp.net-core api response WaitingForActivision - asp.net-core-mvc

Question

Can someone point me into the right direction what I am doing wrong in this Api call? I am getting an odd error that I don’t know what it means. The api call should work as I tested it using VBA and I get a response with the payload. Also any feedback is welcomed.
Id = 190, Status = WaitingForActivation, Method = "{null}", Result = "{Not yet computed}" - this is the response I am getting back from it
