New-MgUserCalendarEvent creating duplicate entries

[TWells94]

Describe the bug

Duplicate entries are getting added for one reseult. The exemple params would be

$CalendarSubject = "New Event"
$StartDate = "yyyy-MM-ddT00:00:00"
$DayAfter= "yyyy-MM-ddT00:00:00"
$AllDay = $True

$params = @{
                Subject = $CalendarSubject
                Body = @{
                    ContentType = "HTML"
                    Content = "Synced from Rapport."
                }
                Start = @{
                    DateTime = $StartDate
                    TimeZone = "Pacific Standard Time"
                }
                End = @{
                    DateTime = $DayAfter
                    TimeZone = "Pacific Standard Time"
                }
                ShowAs = "oof"
                
                IsAllDay = $AllDay

            }

            
            # Create the event
       $Event = New-MgUserCalendarEvent -UserId $UserID -CalendarId $CalendarID -BodyParameter $params

The example screenshot below is from running this once. It seems to add multiple values for some and a single value for others.

I have checked through the results and none of them include duplicate values, i've also removed the "$Event =" and seen it appaears to only add one event but checking the calendar it adds 2.

I've ran it without making the command a variable and it is only showing

Expected behavior

To add one singular value based on the inputs given.

How to reproduce

I have attached a copy of my script but leaving out the inital call (However the example data is copied in the same format)

This is what seems to give 2 copies of the same event entry, at line 112 i even filter out any duplicates based on the start date.

@TWells94 thank you for logging this issue. Please use Invoke-MgGraphRequest cmdlet and let us know if you are still having the same experience. Please use the sample request below. Maybe there is something causing a duplicate web request.

$params = @{
	subject = "Let's go for lunch"
	body = @{

	}
	start = @{

		timeZone = "Pacific Standard Time"
	}
	location = @{

Hi Tim, I've tested using Invoke-MgGraphRequest and it seems to do the same thing. This is the response from one of them. I've checked and it shouldn't of added two of the same event but when I check Jake's calendar it shows like this: ***@***.*** Creating a new calendar event for University Study Attendance on 2024-09-11T00:00:00...

@TWells94 is it possible to switch to a different network environment and execute the request?
