Common Cause of Extension Errors
If you are pulling code off of the internet to put into your extension’s service file, make sure to reformat any shorthand arrow function expressions. If arrow functions stay in the code as is, you may get an “unexpected error” on deployment or a syntax error on activation.
Resolving the Arrow Function Error
Just a handful of characters would have to be added or converted to make the arrow function code workable in SuiteScript 2.x. For example, this line of code to find if an array of objects has some value in the object parameter “name”:
if (arrayOfObjects.filter(e => e.name == "Select This").length > 0)
would be converted into this:
if (arrayOfObjects.filter(function(e) {return e.name == "Select This"}).length > 0)Author: John Baylon
