ps script locate _SMSTSLogPath variable output problem

[radish]

I have a copy item copy script running the output log under windows platform to _SMSTSLogPath. The output log cannot be set successfully. I tried to fail. What should I do?

$start = Get-Date
Function Import-SMSTSENV{
   
        $tsenv = New-Object -COMObject Microsoft.SMS.TSEnvironment
        $TSEnv.Value("_SMSTSLogPath")
        # Create an object to access the task sequence environment
#$tsenv = New-Object -ComObject Microsoft.SMS.TSEnvironment

# Query the environment to get an existing variable
# Set a variable for the task sequence log path
$LogPath = $tsenv.Value("_SMSTSLogPath")
    
        }

#创建日志文件名称
$detetetime = (get-date -format "yyyy年MM月dd日HH时MM分ss秒") 
$applicationlog = "$detetetime" + "HD Tune Pro v5.70 v2 免注册汉化版单文件.log"
