Invisible wall - Trial of the Sekhemas

Doing the Trial of the Sekhemas I found some some invisible wall or unwalkable terrain that don't have any visual. Altougth, in minimap it's marked as some kind of wall or rock blocking the way.

I want to believe that it's a bug because sometimes players aren't looking minimap and relly on what the see in the terrain.

It's really frustrating walk to this terrain and getting stuck while you are fighting mobs.

I have a video trying to walk over this terrain but my character just go around or get stuck in it.
