I can't find where to change the world height for a dedicated server, the wiki page for world generation settings notes that its set at world creation, but don't explain or link to how. I found a MapSizeY value in serverconfig.json, but after changing it to 350 and deleting the world to regenerate I started receiving errors which disappeared when it was changed back.
The errors received are here:
