Roll call can timeout with a 504 gateway time-out error

Roll call can timeout with a 504 gateway time-out error

Canvas white logo

This behavior has been resolved and deployed to the production environment as of 7/13/22.

Description

 

Roll call can fail to load with a 504 Gateway Time-out in courses if it takes too long to load the data.

 

Expected Behavior

 

Roll call should load successfully in courses.

 

Workaround

 

Refresh the page and hope it loads the next time.

 

Steps to Reproduce

 

Prerequisite: Have a course with a decent amount of enrollments, about 500, with each enrollment in multiple sections.

  1. Attempt to load the roll call tool. If it loads successfully, you may need to throttle your network. I was able to consistently have it timeout when using the "Slow 3G" setting within Chrome's network tab.
