influxDB queries return null values instead of real ones while developing a new plugin

Hi all,
I’m a newbie in the development of grafana plugins and I am trying to make a plugin to show in 3D the position of certain devices in motion.

I am using Grafana 7.0 and I have just started with one of the tutorials, so I apologize for my poor experience. The problem is that I have just started to develop the plugin through the template provided with the tool “npx @ grafana/toolkit plugin: create my-plugin” and when testing it in grafana, the queries to influx only return the timestamp and " null "as an associated value.

I find it very strange since the predefined plugins and some extensions that I previously used load the values ​​perfectly and the truth is that I am a bit lost with the theme.

Any help would be greatly appreciated!

You have requested to return null in your query.


Make sure you have data for selected time period and correct query.

Thank you very much @jangaraj. It works

I have recently updated to the new version of grafana and I think that is what has led me to the error, because from what I see in the query results, all the values for instants of time are associated with a null unless there is data in that instant.

Many thanks!
