I get the "Invalid position to teleport" when trying to teleport above 255, eg tp ~ 256 ~.
This is with all type of teleport locations (fixed, relative and directional).
This is for all entities.

@Oval Not a duplicate of MC-170951. Probably related! This is not teleporting below 0, it is teleporting above 255! In the future, please read the bug before leaving a comment!
Maybe it's changed?
