ReferenceError when using third-party library for cloud code in parse

Question

I am trying to include underscore.js in my parse cloud code as below

require('cloud/underscore.js');

And this is the code that use its function

var uniqTest = _.uniq([1,5,4,4,5,2,1,1,3,2,2,3,4,1]);
response.success(uniqTest);

But it's giving me following response

{
"code": 141,
"error": "ReferenceError: _ is not defined\n    at main.js:146:20"
}

Any idea why?

To make it more obvious for others and to give you a chance to mark this as answered :)

It looks like the variable _ is not assigned. You try to execute uniq on _ and since _ seems not to be defined _.uniq will not work. Try to do var _ = require('cloud/underscore.js');
