This article is part of our guide to fixing Google Data Studio reports.
If you're seeing this error on your Google Data Studio reports, making all your charts break, you're not alone.
This is what it shows when you click on See details.
To solve it, please go to edit your report by clicking the button in the top-right corner of your Data Studio report.

Connect a data source again, from scratch to your Data Studio report
Link the data source to the charts
While you will solve the problem, the solution is yet time-consuming: connecting the data source to every chart.
However, there's a trick to making it fast.
If you have too many charts you can type Ctrl+Shift and select every chart you want to link to the data source.
Google Data Studio will let you choose a data source for them in a single click:
