Failed to create SQL script transfer with powershell - sql-server

Question

I've got next error when I'm trying to create database script:
Exception calling "EnumScriptTransfer" with "0" argument(s): "Script
transfer failed. " At C:\temp\Test.ps1:126 char:5
+ $transfer.EnumScriptTransfer();
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : FailedOperationException
Same script is working properly on the other computer. So I assume that the reason is in SQL server version, or rights.
Any ideas?
Code:
echo "Scripting database $dbname .."
set-psdebug -strict
$ErrorActionPreference = "stop" # you can opt to stagger on, bleeding, if an error occurs
# Load SMO assembly, and if we're running SQL 2008 DLLs load the SMOExtended and SQLWMIManagement libraries
$ms='Microsoft.SqlServer'
$v = [System.Reflection.Assembly]::LoadWithPartialName( "$ms.SMO")
$ver = (($v.FullName.Split(','))[1].Split('='))[1];
$vtmp=$ver.Split('.')[0];
echo " SMO version is $ver"
if ($vtmp -ge 9) {
echo " Running SQL 2008, load the SMOExtended .."
[System.Reflection.Assembly]::LoadWithPartialName("$ms.SMOExtended") | out-null
}
$My="$ms.Management.Smo" #
$s = new-object ("$My.Server") $DataSource
if ($s.Version -eq $null ){Throw "Can't find the instance $Datasource"}
$ver = $s.Version
echo " SQL Server version is $ver"
$db= $s.Databases[$Database]
if ($db.name -ne $Database){Throw "Can't find the database '$Database' in $Datasource"};
$transfer = new-object ("$My.Transfer") $db
if ($transfer -eq $null ){Throw "Can't create transfer object"}
$transfer.Options.ScriptBatchTerminator = $true # this only goes to the file
$transfer.Options.ToFileOnly = $true # this only goes to the file
$transfer.Options.ScriptData = $true;
$transfer.Options.FileName = $BackupFile;
$tmp = $transfer.Options
echo " Transfer options are: $tmp"
echo " $transfer"
$transfer.EnumScriptTransfer();
Output:
Scripting database MyDbName ..
SMO version is 14.0.0.0
SQL Server version is 14.0.1000
Transfer options are: ScriptingOptions: ScriptBatchTerminator, ToFileOnly, SchemaQualify, WithDependencies, AllowSystem
Objects, AgentJobId, NoVardecimal, ScriptSchema, ScriptData, ScriptDataCompression, PrimaryObject
Microsoft.SqlServer.Management.Smo.Transfer

Tried to add try-catch block, but this does not work. No idea why:
Try
{
$transfer.EnumScriptTransfer();
}
Catch
{
$msg = $_.Exception.Message;
$innerMsg = $_.Exception.InnerException.Message;
echo $msg
echo $innerMsg
throw;
}
