Object of class CS_REST_Wrapper_Result could not be converted to string in CAMPAIGN MONITOR

Question

Below is json encoded data (but I am passing array) which I am sending. None of the field is not empty. It is creating in LIST but still throwing "Object of class CS_REST_Wrapper_Result could not be converted to string in"

I am not able to remove above error.
