Error Handling

Hi All,

I have a button that deletes an event in Outlook and works just fine. If the event doesn't exist it should notify the user or at least exit. I'm not sure why but I cannot get the IfError function to work. Or maybe I should use something else? Code below. Thanks in advance for any help.

IfError(
With({idCalendarEntry:
 First(
 Office365Outlook.GetEventsCalendarViewV3(
 _myCalendarId,
 Concatenate(DatePicker1_1.SelectedDate, " ", If(Toggle1.Value=true,"00:00:00",TextInput7_1.Text)),
	 Concatenate(DatePicker1_2.SelectedDate, " ", If(Toggle1.Value=true,"23:59:59",TextInput7_2.Text)),
 {search:Concatenate("Event: ",adsComboboxEvents_2.Selected.structureName)}
 ).value
 )
 },
 Office365Outlook.CalendarDeleteItemV2 (
 _myCalendarId,
 idCalendarEntry.id 
 )), Notify ("Event Does not Exist in Outlook Calendar"))

thats some high-level powerapps coding, so i appreciated just reading it.

That being said the code looks good, the problem may be with powerapps itself 😞

if i can break it down into simple terms:

IfError( With({record : First()},Delete), Notify() );

I think whats happening is the IfError is looking at the With() function for an error (which it doesn't error) but the delete function inside the With() does.

I might try this a couple of ways, to work with your code i might try this:
With( {record : First()},IfError(Delete, Notify()) );

or:
UpdateContext({varCalendarToDelete: First("Get calendar")}); If(IsEmpty(varCalendarToDelete), Error(), Delete());

like anything in coding, theres a million ways to do something, and as long as something works and its consistent, then its a perfectly valid solution.

Hope this helps!
