I have a spring - kotlin standalone app. When I run the app or launch the jar everything works fine, my app connects to my supabase Postgresql database. But when I try to run the exe I generate using this jpackage script:

commandLine(
       "$javaHome/bin/jpackage",
       "--type", "app-image",
       "--input", "build/libs",
       "--main-jar", jarPath,
       "--name", appName,
       "--dest", outputDir,
       "--app-version", version.toString(),
       "--icon", "src/main/resources/car_icon.ico",
       "--java-options", "-Djava.awt.headless=false",
       "--java-options", "-Dlogging.file=app.log",
       "--resource-dir", "src/main/resources",
       "--runtime-image", layout.buildDirectory.dir("my-runtime").get().asFile.absolutePath
   )

I get this error:
