Retrieving local scope from call frame

See original GitHub issue

I’m trying to retrieve the local scope data from chrome-remote-interface:

But when logging the frame it shows this:

{
  callFrameId: '5692085564504316912.24.0',
  functionName: '$u',
  functionLocation: { scriptId: '1025', lineNumber: 3, columnNumber: 27701 },
  location: { scriptId: '1025', lineNumber: 3, columnNumber: 27729 },
  url: 'https://x/init.js',
  scopeChain: [
    {
      type: 'local',
      object: [Object],
      name: '$u',
      startLocation: [Object],
      endLocation: [Object]
    },
    {
      type: 'closure',
      object: [Object],
      startLocation: [Object],
      endLocation: [Object]
    },
    { type: 'global', object: [Object] }
  ],
  this: { type: 'undefined' },
  returnValue: { type: 'string', value: '/blocked' }
}

  {
    type: 'local',
    object: {
      type: 'object',
      className: 'Object',
      description: 'Object',
      objectId: '3902945018858753175.1.508'
    },
    name: '$u',
    startLocation: { scriptId: '9', lineNumber: 3, columnNumber: 27701 },
    endLocation: { scriptId: '9', lineNumber: 3, columnNumber: 27730 }
  }

How would you retrieve the e variable containing “pathname” from the local scope?

Component	Version
Operating system	Windows 10
Node.js	14.18.0
Chrome/Chromium/…	Chrome 96.0.4664.45
chrome-remote-interface	0.31.1

Is Chrome running in a container? NO

No problem, I will just iterate over them. Thanks for the quick replies & hard work put into this interface.

Not 100% sure, but I’m afraid you’ll have to iterate over the nested objects and call Runtime.getProperties for each of them. If you can come up with a standalone example I could maybe be more helpful.
