How can I unlock the fixed X and Z rotation of a FollowerEntity?

I am currently implementing a climbing feature using Root Motion via OffMeshLink ladders. It works naturally when the ladder is perfectly vertical, but when the ladder is slightly tilted, the FollowerEntity’s rotation doesn’t adjust to match the ladder’s slope and remains fixed (allowing movement only in a vertical direction). When I call ai.updateRotation = false in the OffMeshLink Coroutine, an error occurs, and the FollowerEntity teleports to the end point of the OffMeshLink.

How can I make the FollowerEntity’s rotation match the slope of the ladder?
(I’m using Recast Graph and OffMeshLink node link2)
