Triggered twice - When an event is added, updated or deleted (V3)



When an event is created (via OWA) in a calendar, the "When an event is added, updated or deleted (V3)" event is triggered twice.


See image below:


The only real difference there is, is the value of "x-ms-apihub-cached-response". (Can't find much info about this.)


I created an extra condition in the flow to catch the version with value "false" and terminate the flow when the value is "true".
This is not reliable. While testing, the event was triggered twice again where both had "true" as value.


Why is it triggered twice? Is this a bug?


How can you make a reliable flow with this trigger?


Thank you!

Hello @Power_Robert 

I just tested using my own calendar and a test flow that uses the same trigger as your flow.

I created an event and the flow was triggered once.

Is there anything special about your calendar that your flow triggers on?

Is there another flow that triggers on the calendar events and does it perform an update?

Kind regards, John
