Hi @ bangorkeith,
Have you problem still exists?
Could you please share a screenshot of the configuration of your flow?
I afraid there is something wrong in your connection.
Please check if you have created a effective connection to your SQL.
You could take a try to create a flow with trigger "SQL - when element is created" , and see if the flow could run to check if the connection to your SQL is effective.
Please let me know if your problem could be solved.
Regards,
Alice Zhang
