Errors: escalationID is undefined and Unable to call as the Notify Number to call from is not define

[Murali Pathuri]

I am working on ServiceNow and Twilio integration. Below is the code that I have written in the Business Rule.

var vars={};

    vars.groupID='fd7ab1c2c360f2100accb275e4013134';

    vars.rotaID='d8b088d6c36032100accb275e4013101';

    vars.escalationID='7f470492c3a032100accb275e40131da';

    vars.rotatime=new GlideDateTime();

    var wrkflw=new Workflow();

    wrkflw.startFlow('9f4476e7ffdb6210ed76ffffffffffe4',current,current.operation(),vars);

Below is the number that I have configured using Twilio.

I am using the following workflow.

On-Call: Assign by Acknowledgement per Rota

I am getting the following errors in the system log

escalationID undefined and Unable to call as the Notify Number to call from is not define

Can anyone help or advise
