PowerCLI commandlet "Get-Snapshot" validation fails when the VM snapshot name starts with square brackets `[`

Products

• VMware vCenter Server

Issue/Introduction

• When attempting to retrieve a virtual machine (VM) snapshot using the PowerCLI "Get-Snapshot" commandlet, the operation unexpectedly returns a null value.
• This issue specifically occurs when the VM snapshot name begins with a square bracket character `[`.

Environment

• VMware vCenter Server 8.x
• VMware vCenter Server 9.x
• VMware PowerCLI 13.x
• VCF PowerCLI 9.0

Resolution

• We are aware of this issue and development team is actively working on a resolution.
• A fix will be included in future release of VCF PowerCLI. 
• In the interim, a workaround has been identified and can be implemented to successfully retrieve snapshots whose names begin with square bracket character `[`. 

Workaround:

The following PowerCLI commands demonstrate the effective workaround:

$vm = Get-VM "NameofVM"

Get-Snapshot -VM $vm | Where-Object { $_.Name -eq "[NameofSnapshot]" }
