Set-PagerDutMaintenanceWindow is not working

[hales8181]

When running the below:
Import-module O:\Powershell\modules\PagerDuty\PagerDuty.psd1
$StartTime = $((Get-Date).ToString("s"))
$EndTime = $((Get-Date).Addminutes(15).ToString("s"))
Set-PagerDutyMaintenanceWindow -id PJ1RHHL -StartTime $StartTime -EndTime $EndTime

I am getting the below error:

Exception calling "ApiPut" with "2" argument(s): "Exception calling "ApiCallBase" with "3" argument(s): "The remote server returned an error: (400) Bad Request.""

Don't worry about setting the start and end times to a string, I tried to keep things as PoShy as possible, so you can leave them in their normal DateTime formats and the library will handle converting it to the proper format. Note - it converts everything to universal time and then formats it to ensure that your time zones are not affecting anything.

So, try this:

Import-module O:\Powershell\modules\PagerDuty\PagerDuty.psd1
$StartTime = Get-Date
$EndTime = (Get-Date).AddMinutes(15)
Set-PagerDutyMaintenanceWindow -id PJ1RHHL -StartTime $StartTime -EndTime $EndTime

As long as that time range is allowed by PagerDuty, it should work. You can see an example of how I tested it (successfully) here. Let me know if that works!

Oh, and also of course make sure your ID is valid if you haven't already.

Edit: Also, even though we don't have the advanced help features filled out for most of the cmdlets yet, if you run Get-Help Set-PagerDutyMaintenanceWindow you'll see the following output which confirms that you should be using the DateTime object, and not a string for the dates:
Set-PagerDutyMaintenanceWindow [-Id] <string> [[-StartTime] <datetime>] [[-EndTime] <datetime>] [[-Description] <string>] [[-ServiceIds] <Object>] [-WhatIf] [-Confirm] [<CommonParameters>]

Ah - A rookie mistake! Thanks! Will give this a go on Monday 👍

Still not working running the above (yes, I checked the service ID), I get:
