SharePoint 2013 Add item to list: The response to this POST request did not contain a 'location' header. That is not supported by this client.

Problem :

When we are trying to insert an item into a newly created SharePoint list using Visual Studio code

We keep getting a NotSupportedException :The response to this POST request did not contain a 'location' header. That is not supported by this client.

If we do a recycle of the SharePoint - 80 website Application Pool in IIS, the program is able to insert the item but after the program is reran for a second time the Exception is thrown again…?
