Cannot read property getTime of undefined error

[SharatSS123]

Geting the above error while trying to view the data as a graph, but am able to view it as a table perfectly.
The data in mongoDB is of the format date time.
Has anyone faced similar issue like this!

Does "ts" variable exists in your collection? And there is values for the timerange that you have specified in grafana?

Also you should check if "ts" variable in mongodb is in date format.

fyi, "ts" is the hard-coded time-series key. I was using "date_time" and trying to get several documents. Ended up rewriting the getTimeseriesResults function in mongodb-grafana/dist/server/mongodb-proxy.js to fix things.

function getTimeseriesResults(docs)
{
  var results = {}
  for ( var i = 0; i < docs.length; i++)
  {
    var doc = docs[i]
    for (const [key, value] of Object.entries(doc))
    {
      if (key =='date_time')
        continue

      if (!(key in results))
      {
        results[key] = {'target': key, 'datapoints':[]}
      }
      else
      {
        results[key].datapoints.push([value, doc['date_time'].getTime()])
      }
    }
  }
  console.log(results)
  return results
