Posted on by Community Power Pla...

When I updated the duration for existing meeting, the error message pop up was showed up.

The update could be completed successfully.

Office365.FindMeetingTimes failed: { "error": { "code": "BadArgument", "message": "Attendees must be added if the organizer is optional", "details": [ { "code": "UnsupportedScenario", "target": "IsOrganizerOptional", "message": "Attendees must be added if the organizer is optional" } ] } }

Hi @Anonymous ,

Can you share more details with your apps?
1. How did you create the meeting? can share the meeting setting?
2. When did you meet the error? after selecting meeting and before selecting the room?
3. Have your ever modify the app template?

I have made a test, but don't have the issue you mentioned, the app works well all the time.
Hopefully you can share more details. so that we can help you better.
Best regards,
Sik

Hi @v-siky-msft

Thank you for your response.

1. How did you create the meeting? can share the meeting setting?
I used the Book A Room template. There are two options, I clicked to book a room for existing meetings. That meeting was created on Outlook. Not by the app.

2. When did you meet the error? after selecting meeting and before selecting the room?
I selected the meeting that i want to book a room for, and some times we need to adjust the meeting time , so as test, I changed the meeting time for existing meeting, and then book a room for it. When I clicked the Book, error happened.

3. Have your ever modify the app template?
No, I have not done any modification for this template.

Hi @Tiffany-Jo ,

I had the same issue. In my case what was happening is that the corresponding value of RequiredAttendees variable was not loading before the FindMeetingTimes connector. So the connector didn't recognize the RequiredAttendees. I believe that you are having the same issue or your function to retrieve the RequiredAttendess address is not working as well. Can you send your function to OnVisible of this screen and the function to OnSelected of this button? When you book for a new meeting, is the same error showing up?

Sorry for reopening an old post, but I'm having this same issue with the same template. below is what is in the OnVisible section:

Set(IsPrevRoomSelect, false);
If(DateTimeRoomChange,
Set(AvailableRoomsCounter, 1);
UpdateContext({ShowLoading: true});
Set(RoomsLeft, Blank());
If(!NoRoomsList,
ClearCollect(AllRooms, Office365.GetRoomsInRoomList(RoomsListsGallery.Selected.Address).value)
);
Set(DateTimeRoomChange, false);
/*
If(CountRows(AllRooms) > 20,
Set(AllRoomsConnector, Concat(FirstN(AllRooms, 20), Address & ";"));
If(CountRows(AllRooms) > 40,
Set(AllRoomsConnector1, Concat(LastN(FirstN(AllRooms, 40), 20), Address & ";"))
),
Set(AllRoomsConnector, Concat(AllRooms, Address & ";"))
);
*/
Set(AllRoomsConnector, Concat(FirstN(AllRooms, 20), Address & ";"));

Concurrent(
ClearCollect(AvailableRooms, Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector, IsOrganizerOptional: true,
Start: StartDateTimeUTC, End: EndDateTimeUTC, MeetingDuration: DateDiff(StartDateTime, EndDateTime, Minutes),
MinimumAttendeePercentage: "1", ActivityDomain: "Unrestricted"})),
If(CountRows(AllRooms) > 20,
If(CountRows(AllRooms) > 40,
Set(AllRoomsConnector1, Concat(LastN(FirstN(AllRooms, 40), 20), Address & ";")),
Set(AllRoomsConnector1, Concat(LastN(AllRooms, CountRows(AllRooms) - 20), Address & ";"))
);
ClearCollect(AvailableRooms1, Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector1, IsOrganizerOptional: true,
Start: StartDateTimeUTC, End: EndDateTimeUTC, MeetingDuration: DateDiff(StartDateTime, EndDateTime, Minutes),
MinimumAttendeePercentage: "1", ActivityDomain: "Unrestricted"})
),
Clear(AvailableRooms1)
)
);
If(CountRows(AllRooms) > 20,
Collect(AvailableRooms, AvailableRooms1)
);
ClearCollect(AvailableRoomsSorted, SortByColumns(First(AvailableRooms).MeetingTimeSuggestions, "Confidence", Descending), If(CountRows(AllRooms) > 20, SortByColumns(Last(AvailableRooms).MeetingTimeSuggestions, "Confidence", Descending)));
ClearCollect(AvailableRoomsConcat, Concat(Filter(First(AvailableRoomsSorted).AttendeeAvailability, Availability = "Free"),
Attendee.EmailAddress.Address, ","), If(CountRows(AllRooms) > 20, Concat(Filter(Last(AvailableRoomsSorted).AttendeeAvailability, Availability = "Free"),
Attendee.EmailAddress.Address, ",")));
ClearCollect(AvailableRoomEmails, Split(First(AvailableRoomsConcat).Value, ","), If(CountRows(AllRooms) > 20, Split(Last(AvailableRoomsConcat).Value, ",")));
ClearCollect(AvailableRoomEmailName, AddColumns(RenameColumns(AvailableRoomEmails, "Result", "Email"), "Name",
LookUp(AllRooms, Email = Address).Name));
UpdateContext({ShowLoading: false});
Set(RoomsLeft, CountRows(AllRooms) - 40 * AvailableRoomsCounter)
);
Clear(AvailableRooms);
Clear(AvailableRooms1)

Hi @DiazjBen

I think that you are having trouble with your Concurrent function. "You can't predict the order in which formulas within the Concurrent function start and end evaluation." (docs.microsoft.com). So the function that retrieves AllRoomsConnector1 could be running after the function that retrieves AvailableRooms1 that needs AllRoomsConnector1.

Try to remove Concurrent function and let the script run in order. Make a test and post here the result.

I'm sorry, could you clarify exactly what I need to do? this is a pre-made template taken directly from samples on the powerapps page, I have very little familiarity with working with the code. I tried just taking out the concurrent container but now I'm getting an error, and I assume I need to replace it with something.

Thank you for your help

Edit

Sorry, it looks like I figured out what the issue was. the problem was that the room list it was pulling from had no rooms in it, so it couldn't set a room as the organizer. adding a room to the list fixed the issue.

First, replace all the code you posted for this one and let me know if it doesn't work.
Set(IsPrevRoomSelect, false); If(DateTimeRoomChange, Set(AvailableRoomsCounter, 1); UpdateContext({ShowLoading: true}); Set(RoomsLeft, Blank()); If(!NoRoomsList, ClearCollect(AllRooms, Office365.GetRoomsInRoomList(RoomsListsGallery.Selected.Address).value) ); Set(DateTimeRoomChange, false); If(CountRows(AllRooms) > 20, Set(AllRoomsConnector, Concat(FirstN(AllRooms, 20), Address & ";")); If(CountRows(AllRooms) > 40, Set(AllRoomsConnector1, Concat(LastN(FirstN(AllRooms, 40), 20), Address & ";")) ), Set(AllRoomsConnector, Concat(AllRooms, Address & ";")) ); Set(AllRoomsConnector, Concat(FirstN(AllRooms, 20), Address & ";")); Concurrent( ClearCollect(AvailableRooms, Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector, IsOrganizerOptional: true, Start: StartDateTimeUTC, End: EndDateTimeUTC, MeetingDuration: DateDiff(StartDateTime, EndDateTime, Minutes), MinimumAttendeePercentage: "1", ActivityDomain: "Unrestricted"})), If(CountRows(AllRooms) > 20, If(CountRows(AllRooms) > 40, Set(AllRoomsConnector1, Concat(LastN(FirstN(AllRooms, 40), 20), Address & ";")), Set(AllRoomsConnector1, Concat(LastN(AllRooms, CountRows(AllRooms) - 20), Address & ";")) ); ClearCollect(AvailableRooms1, Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector1, IsOrganizerOptional: true, Start: StartDateTimeUTC, End: EndDateTimeUTC, MeetingDuration: DateDiff(StartDateTime, EndDateTime, Minutes), MinimumAttendeePercentage: "1", ActivityDomain: "Unrestricted"}) ), Clear(AvailableRooms1) ) ); If(CountRows(AllRooms) > 20, Collect(AvailableRooms, AvailableRooms1) ); ClearCollect(AvailableRoomsSorted, SortByColumns(First(AvailableRooms).MeetingTimeSuggestions, "Confidence", Descending), If(CountRows(AllRooms) > 20, SortByColumns(Last(AvailableRooms).MeetingTimeSuggestions, "Confidence", Descending))); ClearCollect(AvailableRoomsConcat, Concat(Filter(First(AvailableRoomsSorted).AttendeeAvailability, Availability = "Free"), Attendee.EmailAddress.Address, ","), If(CountRows(AllRooms) > 20, Concat(Filter(Last(AvailableRoomsSorted).AttendeeAvailability, Availability = "Free"), Attendee.EmailAddress.Address, ","))); ClearCollect(AvailableRoomEmails, Split(First(AvailableRoomsConcat).Value, ","), If(CountRows(AllRooms) > 20, Split(Last(AvailableRoomsConcat).Value, ","))); ClearCollect(AvailableRoomEmailName, AddColumns(RenameColumns(AvailableRoomEmails, "Result", "Email"), "Name", LookUp(AllRooms, Email = Address).Name)); UpdateContext({ShowLoading: false}); Set(RoomsLeft, CountRows(AllRooms) - 40 * AvailableRoomsCounter) ); Clear(AvailableRooms); Clear(AvailableRooms1)
