When an event is added, updated or deleted - trigger mysteriously stopped working

(0) ShareShare

Posted on by
Hi, I have a flow that detects changes in a secondary calendar, which pulls in a feed from our school calendar. It has been working fine, but now says there is a problem with the trigger, and the CalendarGetOnChangedItemsV3 request may not be supported. When I go to the flow and test it with the last trigger that worked, it still works. The raw input to the trigger in both the failed request and the last successful request is identical:
 
{
    "host": {
        "connectionReferenceName": "shared_office365",
        "operationId": "CalendarGetOnChangedItemsV3"
    },
    "parameters": {
        "table": "MYCALENDARIDGOESHERE=",
        "incomingDays": 14,
        "pastDays": 0
    }
}
 
Any suggestions for where to go from here would be greatly appreciated!
Thanks

    HI,
     
    Can you tell what exact error you get for this trigger? Does user still have access to the calendar? 

    Have you tried to delete the trigger action and recreate it using the action When an event is added, updated or deleted (V3)?

    Also just started experiencing this today- had a number of flows that were working perfectly and now getting an error: Your Office 365 calendar doesn't support the on change trigger.
     
    This automation is highly utilized for our business, would appreciate any suggestions or feedback ASAP.
