Powershell adding a existing holiday to Auto Attendant

Hello

I have to add an existing Holiday to Auto Attendant and have this script 

# Connect to Microsoft Teams
# Connect-MicrosoftTeams

# Variables - Replace with your actual values
$autoAttendantName = "AA_Test"
$holidaySetName    = "Holiday"
#$audioFilePath     = "Paht\test.wav"  # Path to your audio file

# 1. Upload Audio File as Prompt
$content = [System.IO.File]::ReadAllBytes('Path\test.wav')
$audioFile = Import-CsOnlineAudioFile -ApplicationId "OrgAutoAttendant" -FileName "test.wav" -Content $content
$audioPrompt = New-CsAutoAttendantPrompt -AudioFilePrompt $audioFile

# 2. Create Holiday Call Flow with Disconnect Option
$holidayCallFlow = New-CsAutoAttendantCallFlow -Name "Holiday Call Flow" `
    -Greetings @($audioPrompt) `
    -MenuOptions @(
        New-CsAutoAttendantMenuOption -Action Disconnect -DtmfResponse Automatic
    )

# 3. Get existing Auto Attendant and Holiday Set
$aa = Get-CsAutoAttendant -Namefilter $autoAttendantName
$holidaySet = Get-CsAutoAttendantHolidaySet -Name $holidaySetName

# 4. Link Holiday Set and Call Flow to Auto Attendant
Set-CsAutoAttendant -Identity $aa.Identity `
    -HolidaySets @($holidaySet.Identity) `
    -HolidayCallFlow $holidayCallFlow.Identity

# 5. Verify
Get-CsAutoAttendant -Identity $autoAttendantName | Select-Object Name, HolidaySets, HolidayCallFlow

I do get following error
Microsoft.Teams.ConfigAPI.Cmdlets.internal\Import-CsOnlineAudioFile : Expected '{' or '['. Was String: Exception.
At C:\Program Files\WindowsPowerShell\Modules\MicrosoftTeams\7.5.0\custom\Merged_custom_PsExt.ps1:7245 char:13

Where is the mistake
Thanks and have a great day
