Everything was working fine in the openwisp2 server, I have connected multiple devices with multiple firmware versions with different organizations. All the data was coming and stored in the database. I tried adding one more device to the server's with a new organization. It got registered in the Org & it's able to send the data to the server except ping loss and uptime chart. I can see that in the openwisp2 dashboard also. 

But the old devices which are connected to the openwisp2, are showing all the charts with uptime and ping loss charts also appearing in the dashboard. They are working fine.  Only newly registered devices are not showing those two charts. Then I checked Openwisp2.log. Then it has this error. I am not able to replicate this error.

in order to investigate a bug we need to have information like version of the openwisp modules (eg: pip freeze | grep openwisp) and steps to replicate the issue.

Try upgrading to the latest master of openwisp-controller and monitoring to see if it goes away.
