- I am trying to use moment.js inside the handler, but I get an error **moment is not defined**. Moreover, I followed the documentation provided [here](https://github.com/serverless/serverless/tree/master/docs/02-providers/aws/examples/using-external-libraries/node).

- Further, on discussing in gitter, it works for some when they take the npm modules out of node\_modules and put it in the same hierarchy as handler.js. In spite of doing the above change, I still get **not referenced error**.

## Additional Data

- **_Serverless Framework Version you’re using_** : 1.0.0-rc.1
- **_Operating System_** : ubuntu 14.04 trusty
- **_Stack Trace_** : referenceError: moment is not defined.

Can you run `serverless deploy --noDeploy` and inspect the created artifacts if they contain all dependencies and the handler file correctly requires the right path?

It was my mistake. I was not properly referencing the modules. It works properly.
