It happens whenever I try to create a sheet. However, it doesn't seem too important because simply wrapping a try/catch around it fixes the problem. Literally, just wrapping it in try/catch works. But what gives? Has anyone else gotten this behavior?

       ```
        try {
         // originally, there is no try catch, just the line below
         // 
          dvMap[otherAddress].marked = true;  
        } catch(e) {
          console.log('cant set undefined marked blah blah', e)
        }
