Unable to move checkbox while integrating

I am trying to integrate Airtable with Smartsheet using API connections.

In the process, I want to move a checkbox column within Airtable to another checkbox column in Smartsheet.

When I tried with the below code it throws an error of Unable to parse request.

if(record.get('Calendar') != undefined && record.get('Calendar') != null){



columnId: columnMap['Calendar?'],

objectValue: {

objectType: "CHECKBOX",

values: record.get('Calendar')

Is something missing here?
