Describe the bug
UCSM 4.1
Windows PowerShell 5.1
AsBuiltReport.Cisco.UcsManager 2.1

While the report is being generated I receive the following error and the report is not written to disk:
New-AsBuiltReport : Method invocation failed because [System.Management.Automation.PSObject] does not contain a method named 'op_Addition'.
At line:1 char:1

• New-AsBuiltReport -Report Cisco.UcsManager -Target 'x.x.x.x' -Fo ...

•   + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,New-AsBuiltReport
  
  

To Reproduce
New-AsBuiltReport -Report Cisco.UcsManager -Target 'x.x.x.x' -Format Html -OutputFolderPath 'C:\Users\someUser\myApps\AsBuilt\UCS' -Timestamp -Verbose

Expected behavior
I am able to successfully run this against 6248 FIs but not against 6332 FIs. I tested in two separate environments for both FI models.

I ran into the same issue, but was able to resolve it by modifying line 1488 in Invoke-AsBuiltReport.Cisco.UcsManager.ps1 (C:\Program Files\WindowsPowerShell\Modules\AsBuiltReport.Cisco.UcsManager\0.2.1\Src\Public)

$UplinkPortChannelMembers += $UplinkPortChannelMember

to

$UplinkPortChannelMembers = $UplinkPortChannelMember

This issue was on UCS Manager 4.1, but worked fine on version 3.1 - 4.0. After making the change, the reports now worked for 4.1, and also worked on the 3.1 - 4.0 versions. Not sure if it contributed to the issue, but the 4.1 UCS Manager only had one port in the port channel.
