TeamsMeetingPolicy: Export fails on first policy

[TorbenA]

Description of the issue

When trying to export the TeamsMeetingPolicy the export fails on the first policy (Global) the export fails with the Exception "You cannot call a method on a null-valued expression."

I suppose the issue lies within MSFT_TeamsMeetingPolicy.psm1 on line 475. There the Tenant information is missing in the return block.

MSFT_TeamsMeetingPolicy.psm1 Line 470-476:

(...)
            StreamingAttendeeMode                      = $policy.StreamingAttendeeMode
            VideoFiltersMode                           = $policy.VideoFiltersMode
            VoiceIsolation                             = $policy.VoiceIsolation
            TeamsCameraFarEndPTZMode                   = $policy.TeamsCameraFarEndPTZMode
            WhoCanRegister                             = $policy.WhoCanRegister
            Ensure                                     = 'Present'
        }
    }

Compared with e.g. MSFT_TeamsMessagingPolicy.psm1 Line 206-217:

(...)
                Description                                  = $policy.Description

                Ensure                                       = 'Present'
                Credential                                   = $Credential
                ApplicationId                                = $ApplicationId
                TenantId                                     = $TenantId
                CertificateThumbprint                        = $CertificateThumbprint
                ManagedIdentity                              = $ManagedIdentity.IsPresent
                AccessTokens                                 = $AccessTokens
            }
        }
    }

Forgot to mention:
Adding the follwing lines to MSFT_TeamsMeetingPolicy.psm1 line 476 fixes the issue:

            Credential                                   = $Credential
            ApplicationId                                = $ApplicationId
            TenantId                                     = $TenantId
            CertificateThumbprint                        = $CertificateThumbprint
