Hi, I also use same code. Its working fine for chrome, but for Firefox its not working
When I try to log session object value at line 34 it gives me something like that
{ status: -1, value: 'HTTP method not allowed', errorStatus: -1, error: 'An unknown error has occurred.', httpStatusCode: 405 }

So session.sessionId become undefined and end to end test case gets failed.

I try to upload file on SauceLab environment.

@DineshChopra to make it working in Firefox I removed the session callback (line 34) and used api.sessionId directly:

.on('finish', async () => {
  const file = Buffer.concat(buffers).toString('base64');

  const opt = {
    path: `/session/${api.sessionId}/file`,
    method: 'POST',
    data: { file },
  };

  Nightwatch.transport.runProtocolAction(opt).then(handleResult(cb));
});

@rosariosm still not working for me for firefox. Working fine for chrome.
