Benchmark runs, but fails at end when converting output to CISAuditResult object

[ashmatash76]

Getting an error at the end of the benchmark test:

PS C:\Windows\system32> $auditResults = Invoke-M365SecurityAudit -TenantAdminUrl "https://-admin.sharepoint.com" Performing the operation "Assert-ModuleAvailability" on target "Modules: ExchangeOnlineManagement, Microsoft.Graph

Microsoft.Online.SharePoint.PowerShell, MicrosoftTeams".

VERBOSE: An error occurred during the test 5.1.8.1:
Cannot process argument transformation on parameter 'Result'. Cannot convert value
"System.Management.Automation.PSCustomObject" to type "System.Boolean". Boolean parameters accept only Boolean values
and numbers, such as $True, $False, 1 or 0.

Looking at the test results in question:
PS C:\Windows\system32> $auditResults | where { $_.rec -eq '5.1.8.1' }

Status : Fail
ELevel : E3
ProfileLevel : L1
Automated : True
Connection : Microsoft Graph
Rec : 5.1.8.1
RecDescription : Ensure password hash sync is enabled for hybrid deployments
CISControlVer : v8
CISControl : 6.7
CISDescription : Centralize Access Control
IG1 : False
IG2 : True
IG3 : True
Result : False
Details : An error occurred while processing the test.
FailureReason : Initialization error: Failed to process the test.

I can see the test failed to run, should that interfere with the transformation of the resulting system.object[] to the expected "CISAuditResult" object? The export command requires a CISAuditResult object and fails otherwise.
