Since the last update, I noticed that Flair-bi is slower to load the data into the Dashboard.
I scaled up the services flair-bi (2) and flair-engine (2), but sometimes the dashboard loads as expected and sometimes doesn't at all.
I can see the error below when it doesn't load and I am not able to see any other error in the logs, it just shows the loading icon, but it doesn't bring the result.
flair-bi-77849c8bbc-vslsd flair-bi 2020-09-10 12:26:24.769 ERROR 8 --- [ XNIO-1 task-2] o.s.w.s.s.s.DefaultHandshakeHandler : Handshake failed due to invalid Upgrade header: null
This also happens when I try to apply a filter selecting a value in the charts and executing the filter, it shows the loading icon but doesn't return the result and I also cannot see errors in the log apart from the above.
At this point, I am not able to analyse the issue as I cannot see errors in the log and also I cannot see what queries flair-bi is executing in the database.
Is there any idea what I could do to progress the investigation?
