Troubleshooting Zapier Error: Populate at least one field to add a record

Hi - I am new to clay. I am trying to use Zapier to push new google sheet rows into clay by creating a new record in clay. I have set up the trigger in Zapier (google sheet row) successfully but am having trouble with the “Create Record in Table” zap. The error I am getting is “Populate at least one field to add a record”.
