Improve Insights data loading error - Backend
Summary
When Insights loads data there might be query timeouts due to query volume. We should inform users that the chart wasn't loaded because query tries to load too much data and suggest them to reduce data volume. More info here
Proposal
When Insights query timeouts API should return custom error message. This error message should be displayed to user instead of corresponding chart data.
