Why I am not able to process the list type input inside the action script?

[Manikantahere]

I have a input i.e. list user type where people can select multiple users. 

While I am trying to fetch the mails of the users I am not getting the result? What I am missing here?

Hi @Manikantahere 
Input type is String. So you need to convert that into array before iteration.
Try below script. 
Input-> Approver sys ids. Type: String

Output-> Approver email ids. Type:String

Script:

var approverEmail = [];
var approvers = inputs.approver_sysId;
var approver_arr = approvers.split(",");
for (var i = 0; i < approver_arr.length; i++) {
    var user = new GlideRecord("sys_user");
    user.get(approver_arr[i]);
    approverEmail.push(user.email);
}
outputs.approver_emails = approverEmail.toString();

Regards,

Siva

No luck, it is not working.

Approver input field type is List referenced to user table where as output is a string only.

Please see the below image how I am giving.

@Manikantahere 

what's the input type for the input variable of script step?

since you are passing list of users, it's an array of objects I believe of GlideRecord

what came in logs?

If my response helped please mark it correct and close the thread so that it benefits future readers.

I don't think I can set the input type for the input variable of script step. but action input type for the approver is List reference to user table.

Yes, Its coming as Glide Record object.
But not going into for loop when I executed the script.
