Hello @JFM_12 - Thanks for bringing this issue to our attention.

The error occurs because Import-CsOnlineAudioFile expects the -Content parameter as a byte array, but the way you're passing it may not be compatible with the cmdlet's internal processing.

Fix:

Replace this line:

$content = [System.IO.File]::ReadAllBytes('Path\test.wav')
$audioFile = Import-CsOnlineAudioFile -ApplicationId "OrgAutoAttendant" -FileName "test.wav" -Content $content

With:

$audioFile = Import-CsOnlineAudioFile -ApplicationId "OrgAutoAttendant" -FileName "test.wav" -Content ([System.IO.File]::ReadAllBytes('Path\test.wav'))

Please let us know if you have any further query.
