Server Javascript error Cannot find function split in object. Release or Environment All releases

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(',');
