[GitHub] [superset] ValentinC-BR opened a new issue #16742: Charts in dashboards are subject to frequent errors with Chrome users

ValentinC-BR opened a new issue #16742:
URL: https://github.com/apache/superset/issues/16742


   Since Superset 1.x, all our Chrome users get recurrent errors on charts loading (in dashboards), forcing them to refresh the page
   
   ### Expected results
   
   All the charts are displayed without errors.
   
   
   ### Actual results
   
   The following error is (randomly ?) displayed : Unexpected error
   
   When we click on "See More", here's the error we get : 
   
   > \<html>
   >\<head>\<title>502 Bad Gateway\</title>\</head>
   > \<body>
   > \<center>\<h1>502 Bad Gateway\</h1>\</center>
   > \</body>
   > \</html>
   > \<!-- a padding to disable MSIE and Chrome friendly error page -->
   > \<!-- a padding to disable MSIE and Chrome friendly error page -->
   > \<!-- a padding to disable MSIE and Chrome friendly error page -->
   > \<!-- a padding to disable MSIE and Chrome friendly error page -->
   > \<!-- a padding to disable MSIE and Chrome friendly error page -->
   > \<!-- a padding to disable MSIE and Chrome friendly error page -->
   
   Important : 
   * This can happen in one ore several charts.
   * This usually disappears when refreshing the page once or twice
   * This only happens in dashboards (we've never had this issue in "View chart in explore")
   * This seems to concern only Chrome users (Firefox users did not complain about this)
   
   
   #### Screenshots
   
   What we can see in dashboards :

   #### How to reproduce the bug
   
   1. Use Google Chrome
   2. Open any dashboard
   
   
   ### Environment
   
   superset version: 1.3.0
   python version: 3.7.9
   node.js version: doesn't apply, I run on Kubernetes, using gunicorn as server
   source : Athena

   Hi @vivek-kandhvar ! Nice to see we're not alone :wink: On the whole, I can answer we did not change much configuration when moving to 1.x (1.1 and 1.2 in our case). But our config is constantly evolving so I cannot guarantee it with perfect certainty.

   @ValentinC-BR Even we are seeing this issue with 1.3.0 very frequently. Just wanted check if you had not faced this issue prior 1.x. Can you confirm if you haven't changed anything before moving to 1.x?

   @ValentinC-BR This error is being thrown by nginx or whichever proxy is in front of superset. 502 means the service(superset) is unavailable, either the superset server hash crashed (out of memory or cpu, etc.), or is too busy to serve your request. This is error is due to your deployment set up and there's nothing we can do on the superset application side, at least not without the log/stack trace for what actually caused the service to report as unavailable. 
   
   Closing this issue as this is not actionable from an application perspective. If you do a root cause analysis that results in an issue with the superset application please feel free to reopen the ticket. For now I would suggest scaling up your superset deployment, either vertically or horizontally to see if that fixes it.
