I'm using power automate to wire up some info into smartsheets. I have everything working so far but multi contact list and multi pick list. The contact list error I get is this: The value "John smith" could not be saved in column "Assignment". This column is restricted to MULTI_CONTACT_LIST values only. The name is definitely there. Have tried email addresses, arrays, objects, strings, nothing works.
What format are these columns expecting data in? I can't find anything usable anywhere.
