A bug which should have been solved a week ago
Recently, we have a DS ticket that said a user got banner error periodically on the home page. That means we got some BE errors on API requests. I checked NewRelic and nothing exception was found. I checked error logs on our server and only a few 500 errors. I can’t find further information about these errors. So I believe it was caused by an unstable network or it might be caused. I was not working on that task.
Until yesterday we were going to solve a cache memory issue and I still not realized that was caused by cache memory. After I had submitted that PR of fixing cache memory, I decided to look that DS ticket again. I notice there’s some clue. I could find banner errors on fullstory and that means we did get some request errors. Then I checked request logs on Cloudflare and here are unsuccessful requests.
