Need to return streamlined json from query

When you execute JSON.stringify(result.records) you are serializing the 'records' object from a list. Each record apparently has additional metadata to describe the record in addition to the you returned as 'tag'.

If you want to look at just your data from each record, try something like this:

result.records.forEach(record => {
      console.log(JSON.stringify(record.get('tag')))
    })
