Returning error if no meeting room is available

(0) ShareShare
ReportReport
Posted on by MirTechDev 36

Hi,

 

I'm trying to understand why the Book-a-Room app from Microsoft is failing all the time when there's no room available inside a group. Here does the error happen:

 

ClearCollect(AvailableRooms; Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector; IsOrganizerOptional: true; 
 Start: StartDateTimeUTC; End: EndDateTimeUTC; MeetingDuration: DateDiff(StartDateTime; EndDateTime; Minutes);
 MinimumAttendeePercentage: "1"; ActivityDomain: "Unrestricted"}));

 

 

The error is:

 

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"
 }
 ]
 }
}

 

 

Anyone with any clue how I can deal with this error? I tried to use the new IfError function:

 

IfError(
 ClearCollect(AvailableRooms; Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector; IsOrganizerOptional: true; 
 Start: StartDateTimeUTC; End: EndDateTimeUTC; MeetingDuration: DateDiff(StartDateTime; EndDateTime; Minutes);
 MinimumAttendeePercentage: "1"; ActivityDomain: "Unrestricted"})), Notify("No rooms available.", Error));

 

 

But keep getting 'The formula contains 'ParenClose' where 'Error' is expected'

 

So any help is highly appreciated!

    @MirTechDev ,

    Why don't you avoid the empty room list situation:

     

     

    If(
 IsEmpty(AllRoomsConnector);
 Notify("There is no room inside the selected group !");
 ClearCollect(AvailableRooms; 
 Office365.FindMeetingTimes({RequiredAttendees: AllRoomsConnector;
 IsOrganizerOptional: true; 
 Start: StartDateTimeUTC; 
 End: EndDateTimeUTC; 
 MeetingDuration: DateDiff(StartDateTime; 
 EndDateTime; 
 Minutes);
 MinimumAttendeePercentage: "1"; 
 ActivityDomain: "Unrestricted"})
 )
);;

     

     

    Hope it helps !

    Hi @gabibalaban 

    Thank you for the answer.

    There's something wrong in the code snippet you provide me, can you help me find this?

     

    Keep getting 'function if has some invalid arguments'

    @MirTechDev ,

    Yes, there was a double quote missing in Notify() function.

    Also, I think that you ;; at the end of my code. 

    I corrected my previous post.

    Still keep getting another error:

    Invalid number of arguments: recieved 1, expected 2 or more.
     
    Here is the whole concurrent-function:

     

     Concurrent(
 If(
 IsEmpty(AllRoomsConnector);
 Notify("There is no room inside the selected group !");
 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)
 )
 );;​

    @MirTechDev ,

    We are inside of a Concurrent() function, please replace ;; with ; at the end of my formula.

    Keep getting another error 😞
    Invalid argument type (Table). Expecting a Boolean value instead.
