There will be more to this that requires further troubleshooting.

We cannot reproduce the issue here or in development.

Media items will only have a corresponding Thread relation if they’ve been added through media mirroring.

The Thread relation wouldn’t resolve if the Thread no longer exists but that shouldn’t happen in normal operation.

Hi Chris,

I found the problem. The issue was in one of my add-ons, I was hiding the reaction bar data (which user has reacted to a post). To fix the error, I wrapped the code in a <xf:if is="$template == 'thread_view'"> and that corrected the issue.

Sorry to have wasted your time.
