Explanation needed: Why is parsed stack different when using StackTrace.fromError with option offline=true and offline=false?

[AldinaSculac]

Hi all, I need bit of a help when using stacktrace-js in my React Native project.

Working with with Simulator iPhone 14 Pro, iOS 16.2.

"dependencies": {
    "@react-navigation/bottom-tabs": "6.0.9",
    "@react-navigation/native": "6.0.6",
    "@react-navigation/stack": "6.0.11",
    "hermes-engine": "0.11.0",
    "jetifier": "2.0.0",
    "react": "18.1.0",
    "react-native": "0.70.6",
     "stacktrace-js": "2.0.0"
  }

When using StackTrace.fromError and setting offline=true I get this as the first object in a stack array

  {
   "columnNumber":32,
   "fileName":"http://.../index.bundle?platform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=com.myapp",
   "functionName":"onPress",
   "lineNumber":101677,
   "source":"  at onPress (http://.../index.bundleplatform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=com.myapp:101677:32)"
  },

If I set the offline option to false I get this:

  {
   "columnNumber":60,
   "fileName":"http://.../myapp/src/screens/MainScreen.tsx",
   "functionName":"MainScreen",
   "lineNumber":36
  },

What I get when using offline=false aligns with logbox message.

Can anyone explain why I get the difference, and why is in offline=false mode functionName the same as the screen name?
