How do I access multiselect dropdown values from a dialog in a service playbook?

Hello,

I have a service dialog with two dropdowns that is provisioning an ansible playbook service. One of the drop downs is standard, one is multiselect. The playbook doesn’t seem to pick up the values from the multiselect - instead always using the default value. The standard dropdown, and indeed all the other variables from the dialog, are working as expected.
Are there any special considerations when working with a multiselect dropdown and an ansible playbook? FYI I am running ivanchuk

Thank you in advance
