data not getting populated in the dashboard

Data store is yellow with this message: No data was found in the short term search for the Search History storage. This likely indicates that either the backfill script is not scheduled to run, or some sort of error while running it. If the script shows Validation Success below, you should check the Troubleshooting TSIDX Population dashboard.
