Actions to reproduce (if known)
Register a command using Commands#register(LiteralCommandNode) and inside the commands ArgumentBuilder#requires() check, try to access the command-sources location.
Then join the server with a player with full permissions (op).
For this test i set-up a fresh paper-server, installed BlueMap, gave myself op-permissions and joined the server:
The error is then thrown here
(commands are registered here).
