Split() method in workflow does not work

[Nancy8]

The requirement is to get a list of users from catalog item form and assigned them to groups.  I used the variable type:list collector for variable "Select User (g_1_user).  In my workflow, I used "Run Script" to run the following script:

In logs, I got a list of user returned: , but when I was trying to use "split(",")" method to split each user, I got "undefined" the error (size====undefined).  It seems "Split() " doesn't in workflow.  Any suggestion how to split a list of users in workflow?
