Got Error: socket hang up

[akshitkrnagpal]

Hi

We have recently integrated mixpanel-node to send serverside events. Most of the events are being recorded but once in a while we get the following error and the event is NOT recorded.

ERROR   /node_modules/mixpanel/lib/mixpanel-node.js:156 mixpanel        Got Error: socket hang up

We would like some guidance to make sure we are sending all events without any data loss.

This mainly happens in serverless functions due to the calling route closing before completing the request to mixpanel.

As mentioned in (#175 (comment)), Wrapping the tracking code with a promise solved this issue for me.
