Decryption of individual files via CLI not possible?

I'm trying to decrypt only few files via CLI but even though I manually provide the encryption key, the tool wants the game directory. This is weird because it works fine for encrypting few files via CLI.

Here's the error I get:-

Here's the code for my CLI:-

@echo off
title RPG Maker MV;MZ Decrypter ^| Command-Line Tool by RedAISkye
cls
set currentDir=%~dp0
cd /d %currentDir%
echo.
echo  RPG Maker MV;MZ Decrypter ^| Command-Line Tool by RedAISkye
echo.
echo.
echo  Enter project path: (Leave blank ^for default "%currentDir%input")
set /p projectPath=
echo.
if "%projectPath%"=="" (
    set projectPath=%currentDir%input
    echo  Enter encryption key: ^(Can't be left blank^)
) else (
    echo  Enter encryption key: ^(Leave blank ^for default "auto"^)
)
set /p encryptionKey=
if "%encryptionKey%"=="" set encryptionKey=auto
echo.
echo.
java -jar "RPG Maker MV Decrypter.jar" encrypt "%projectPath%" "%currentDir%output" true %encryptionKey%
java -jar "RPG Maker MV Decrypter.jar" decrypt "%projectPath%" "%currentDir%output" true %encryptionKey%
echo.
