TunnelPasswordPlain not working in PowerShell script

My WinSCP GUI works well for manfully inputting both Tunnel Username/password and access username/password. But the generated PowerShell script doesn't work. I added password into the script file. But it seems the program doesn't get Tunnel password, it's still say (Password: No).

See below log:
. 2021-10-21 09:22:24.189 Command-line: "C:\Program Files (x86)\WinSCP\WinSCP.exe" /console=5.19.2 /consoleinstance=_21264_257 "/log=C:\temp\log\WinSCP.log" "/ini=nul" "/command" "open scp://123_scp:***@142.123.001.123/ -hostkey=""ssh-rsa 2048 Y3P6mwpIMDu64ngZsiqOe9VVVK4vmnCubTg/T3YZIXE="" -rawsettings Tunnel=1 TunnelHostName=""142.001.001.12"" TunnelHostKey=""ssh-ed25519 255 +8C0z8OHdWLr0CM/o7VwV5jQ64Hzdck+rhTyPTy9bd0="" TunnelUserName=""q4mh8k9"" TunnelPasswordPlain=***" "lcd C:\Steven\Projects\SCPC_Output" "cd /home/123_scp/10_Seedfile_Oct_2021" "put CSPC_Adding_List.csv" "exit" 
I did use TunnelPasswordPlain, but the log says the password is No:

The pre-entered password in URL works, but Tunnel Password not working

The Windows PowerShell console always ask me to manually enter password, then the following steps work well including the authentication of username/password in the URL.

See the console recording:
PS C:\temp\script> .\Transfer_Files.ps1
Opening tunnel...
Searching for host...
Connecting to host...
Authenticating...
Using username "username123".
Authenticating tunnel through 142.245.207.12
Password:
Authenticated.
Connecting through tunnel...
Searching for host...
Connecting to host...
Authenticating...
Using username "123_scp".
Authenticating with pre-entered password.
Authenticated.
Starting the session...
Session started.
Active session: [1] 123_scp@142.245.206.141
C:\Steven\Projects\SCPC_Output
/home/123_scp/10_Seedfile_Oct_2021
CSPC_Adding_List.csv      |           5 KB |    0.0 KB/s | binary | 100%
Success
PS C:\temp\script>

Re: TunnelPasswordPlain not working in PowerShell script

Doesn't your password contain some special characters than may need escaping in PowerShell or in WinSCP?

Re: TunnelPasswordPlain not working in PowerShell script

I already converted the special character of my password into ASC code such as %21, etc. Both 2 passwords have the special character, the other password works well, only TunnelPasswordPlain has problem.

Re: TunnelPasswordPlain not working in PowerShell script

It seems that you are running WinSCP from command-line. Why don't you use WinSCP .NET assembly? It would take care of correct encoding for you.

Anyway, you can try to enable password logging using /loglevel=*. That might help you with debugging the problem.
