Unable to write data to multiselect dropdown fields in Smartsheet

I’m using Zapier to write data to a Smartsheet in response to a webhook.  Works fine except if one of the fields is a Dropdown field in Smartsheet with “Allow multiple values” set to True. 

The error received when testing the Zap is “Value is not supported for this column type. Use objectValue instead”.  I think this means that the Smartsheet API requires multiselect field values to come in as an object not a string, but Zapier is sending everything as strings. 

Has anyone else encountered this?  Below is an example of the field that throws an error when Zapier tries writing to it.

In Zapier, when you are setting up your Smartsheet action, is there a dropdown displaying each of those occupations with a grayed out string of numbers and letters, as seen below?

If so, you’ll want to either add a code step or use a Lookup Table (in Formatter by Zapier utilities) to map the string from your webhook (ie, “Artist”) to the corresponding object ID (ie. “6148f88b2fd73cd680f9fec9” in my screenshot).
