Not generating lighthouse reports

[Srihari88]

I did try in my project but I'm getting error. This error is coming when I used the lighthouse in .gimbalrc.yaml file. If I removed the lighthouse it used to work

Error: connect ECONNREFUSED ::1:49716
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1136:16) {
  errno: -61,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '::1',
  port: 49716,
  friendlyMessage: undefined
}

Not able to see lighthouse results.
