Getting json payload cannot be empty when adding a list via api

[RonC376]

Hi all, I'm trying to add a list identifier via the API and I'm getting a "json payload cannot be empty error. This is the content of my log file from my application which shows the actual request and reply sent on the wire:

The <api_key> and <token> values are obviously correct since the server returns the current list details as requested. Any suggestions as to what might be wrong?
