Custom emojis broken after upgrading from 9.11.6 -> 10.3.1

Troubleshooting
1

Summary
After upgrading, custom emojis are missing. Requests to https://<my.server>/api/v4/emoji//image are 404’ing.

Steps to reproduce

  • Server running Ubuntu 22.04
  • The upgrade was from 9.11.6 → 10.3.1, I likely did not look at the output of step 7 of the upgrade guide clearly enough.
  • I see little of interest in logs

Additional details
I’m unclear how to restore the image files as I use S3 for file storage, and had thought emojis were stored there.

I have an old server backup with the emoji folder preserved with the correct emoji id’s that I’d prefer to restore so as to not need to manually re-upload every emoji (and lose the emoji history if I have to delete the old emojis), but I’m not sure where to restore it to.

I’ve tried restoring the files into /opt/mattermost/client/emoji/<id>/image and also /opt/mattermost/data/emoji/<id>/image, but it doesn’t seem to fix the issue.

Any help is appreciated!

I’ll look into this a little.

Hmmm okay I managed to fix this, but I’m not sure how I did it. I suspect something broke in my S3 connection, even though I thought had tested the connection.

Something in the following steps resolved the issue:

  1. Changing from S3 storage → Local file storage → back to S3 storage
  2. Fiddling with S3 connection parameters until it was green again
  3. Purging all caches within System Console
  4. Manually restarting the Mattermost service with sudo systemctl restart mattermost a couple of times
