The error message tells you what you need to know so far: whatever you're trying to write using your WTDS node is apparently empty. If you can post a screenshot of your process instance data, that would help us provide further insight, because at the moment there isn't much for us to go on.
Share the process instance data,
You can find the that by clicking on the process details in toolbar of particular process instance.
