when trying to set a custom user - Avatar Jira throws an Error

[Deleted user]

Edit - I have also upgraded Jira server to the latest (8.5.0), no change

I can load project avatars no problem, but when I try to set the avatar for users, I get the following:

I have checked the image sizes, formats, and have changed between Safari, Chrome, and Firefox.  the same avatars that work for projects, fail for users.

Hi @[deleted] 

Have you checked the atlassian-jira.log file?

I reckon there would be something meaningful there which will give us clue to fix the problem.

Sorry, I forgot to add those details.  Nothing in the standard logs, but this was in atlassian-jira-security.log, which was the most recently touched log file after my latest attmept:

Sorry, those security logs do not give a clue.

If you change default log level to DEBUG, it might be helpful, but I'm not sure though.
