That is more clear than the previous output (without DEBUG). So, there is a NaN in a position. Looking in the entities.json, it is on entity 136. (How it got there I can't tell.)
Simplest solution: Run the client, login to the master, but not to a server, edit the entities.json (can just remove that entire line with entity 136, or fix the position, as you wish), and do
/upload_asset.
