Odd error message

[Hax0rG1rl]

Hi there,

Trying to check a simple JS file I got this error:

/jsprime/jsprime-node/engine.js:1530
            if (node2.argument.name != undefined)
                               ^

TypeError: Cannot read property 'name' of null

    at traverseMini (/jsprime/jsprime-node/engine.js:91:17)
    at getFunctions (/jsprime/jsprime-node/engine.js:1527:9)

Any ideas how to solve this?

Regards.

I hope by now you would have got the solution
If not
change if (node2.argument.name != undefined)
to if (node2.argument!=undefined & node2.argument.name != undefined)

Reason : By the error msg its simple that when traversing through AST there are cases where the node may have a null argument. Since we are trying for name object it is throwing error.
