500 error when going to your world > map

Steps to reproduce…
1) Create a new world.
2) Go to the map in the navigation bar on the left.

3) Get 500 error message.

I have tried this on Brave Browser v1.81.135 and Firefox v141.0.3.
My OS, if it matters is windows.
The issue is reproducible after clearing my cache in both browsers and reproducible in incognito, in both browsers.

I have also tried this on another device (mobile) using Brave browser, and got the same result.

This appears to be a genuine server issue, not a device or browser issue.
