Deluge function getRecordById is missing all Multiselect fields

I'm running a custom function inside a CRM Contact Workflow. I'm able to use getRecordById to get the contact fields, but all of the Multiselect fields are missing in the result. All other fields are present. The code is simple:

  1. contactDetails = zoho.crm.getRecordById("Contacts",contactId);
  2. email = contactDetails.get("Email"); // returns the correct email
  3. lifetimeProducts = contactDetails.get("Lifetime_Products_Owned"); // returns null, as does every other Multiselect field
