Cause

The problem is that the split method is not available on list objects. 

If you look at mozilla's documentation, the split method is a method that exist on string objects. 
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split 

Resolution

---

To fix the issue, use 'toString()' in order to allow the glidelist object to access the split() method.

For example, if you are using the method directly like:

data.test_array = data.fields.split(','); 

Change it to:

data.test_array = data.fields.toString().split(',');
