Creating duplicate Trello cards from Outlook calendar

I have created a flow to create a Trello card when a Calendar event is created in Outlook.  This works a treat and is correctly formatted using all of the dynamic content builders in the FLow Builder App - except that it is creating two cards on the Trello board.


Any tips for how to prevent this from happening?


Screenshots below show the Flow trigger setup:

Hi sam_gledhill,


I created a similar flow with you to test this issue on my side. When I created an event to run the flow, I found there was only one card created on my Trello board.



Please make sure you didn’t create two same events at a time. Could you try again to run the flow on your side?


If you are still getting this issue, please send me a screenshot of your flow run status likes this:
