LeanFT not able to find windows or screen when running from command prompt - Terminal Emulator IBM Application

Question

Am running automation on terminal emulator IBM PCOMM application, framework consists , maven + leanft +cucumber+ java + junit , when i run the feature from runner file , i am able to execute the tests , but when i using maven command through command prompt , it is opening the application but not able to type anything

maven command:

mvn clean  verify -Dcucumber.filter.tags="@Mainframe"

below is the command used for launch :

        ModifiableSDKConfiguration sdkConfig = new ModifiableSDKConfiguration();
        sdkConfig.setServerAddress(new URI("ws://localhost:5095"));
        SDK.init(sdkConfig);
        File file = new File(filePath);
            java.awt.Desktop.getDesktop().open(file);

to insert text :

screen.describe(Field.class,
            new FieldDescription.Builder().startPosition(row, col).isProtected(false).visible(true).build())
            .setText(text);
screen.sync();

Leanft version : 14.53

Screen logic:

Window teWindow = Desktop.describe(Window.class, new WindowDescription.Builder().shortName(new RegExpProperty(".*")).build()); 
Screen screen = teWindow.describe(Screen.class, new ScreenDescription.Builder().label(new RegExpProperty(".*")).build()); 

Error:

com.hp.lft.sdk.ReplayObjectNotFoundException: Cannot find the "Terminal Emulators Field" object's parent "Terminal Emulators Window" (class TeWindow). Verify that parent properties match an object currently displayed in your application.

If i try opening application with LeanFT Terminal Emulator Technology , am getting below error :
