Dynamic content from calendar event "starttime" not recognised as a valid

(0) ShareShare

Posted on by
I'm using the formula below in a flow to allow automated forwarding of calendar events
 
convertFromUtc('2026-04-17T20:00:00+00:00', 'UTC') [ I appreciate I am converting from UTC to UTC here but simply trying to debug]
 
or
 
convertFromUtc(triggerOutputs()?['body/start'],triggerOutputs()?['body/timeZone'])
 
with the string copied directly from dynamic content. 
 
I'm getting the following error:
{"status":400,"message":"The string was not recognized as a valid DateTime. There is an unknown word starting at index 0.\r\nclientRequestId: 44aba0d2-86f3-4909-b34d-27f409572d5c","error":{"message":"The string was not recognized as a valid DateTime. There is an unknown word starting at index 0."},"source":"office365-we.azconn-we-003.p.azurewebsites.net"}

    Your expression needs to be in this format convertFromUtc('2026-04-17T20:00:00Z', 'UTC') 
     
    Although, what you have would not be very useful as it converts UTC to UTC, which I think you know and are just using as an example. I think you want something like this convertFromUtc('2026-04-17T20:00:00Z', 'Eastern Standard Time')
     
    You need to get your trigger output values to match this for the expression.
