Good morning!  
When a I clic on a tab of the tab strip component, will open a window that is going to show a Piechart with stadistics and a table with information, both components have queries but I got this error, I am not sure if is for the chart.

Also, my window is very slow to charge the complete window and sometimes ignition get slow, I tried to remove or change some things that were consuming memory.

Can someone explain me please?  
And let me know if you need to see the queries.

The dataset for your piechart has a null value (None) in it somewhere.

You may need to upgrade to Ignition 8.1.14 or later. It looks like you're running in to a bug that we fixed in that version.

I'm not sure I understand your question. But there's no work around for the bug and the upgrade is free, if that helps.

That doesn't exist, however there are changelogs that list the bugs fixed in each release.

Each version on the downloads page has a release notes link: [Current Ignition Release | Inductive Automation](https://inductiveautomation.com/downloads/ignition/8.1.30)
