@akaDJon Ah, you're on release/2020-11-18.29. Try the latest release?

akaDJon commented 2 years ago

Troubleshooting:

  • Does the error persist on reload?
  • What does document.getElementById('gradebook_grid') return in the browser console?

not persist. one load everything ok, the next load fail, and next again ok image

We're seeing this issue as well on origin/stable/2021-08-18 of the code when using Chrome.

@akaDJon - Looking the Canvas Release Notes it appears to be an issue that they've fixed in a more recent version.

This behavior is resolved in the 2021-12-15 deploy.

I was able to deploy a newer version of canvas origin/stable/2022-02-16 and I am not able to reproduce the issue any longer.
