Cannot index into a null Array Error

I'm getting this error for Apple Airport Extreme Router.

Cannot index into a null array.

@bellicose100xp That happens when the MAC-Address is not in the official Vendor List... I try to assign the first entry in the list which matches the MAC-Address.

This should fix it:

try {
$Vendor = (($MAC_VendorList | Where-Object {$_.Assignment -eq $MACVendor_Search})[0])."Organization Name"
}
catch {}

New version including this fix is released:
