Not getting full stack trace

[goelvivek]

Hi,
I am using node-gcm module.
I have enable longjohn. But I am not getting full stack trace
Stacktrace look like

..................
[8] => at g (events.js:175:14)
[9] => at EventEmitter.emit (events.js:95:17)
[10] => at parserOnIncomingClient (http.js:1663:21)
[11] => at parserOnHeadersComplete (http.js:122:23)
[12] => at socketOnData (http.js:1556:20)
)

What could be the issue ?
