After beating The Dragon Ender a bridge leading to the city of the ender appears (nothing abnormal)

Once the path to access it built I decide to throw a pearl in the bridge to teleport me.

But instead of being teleported to the cities of the ender, I reappear next to the catwalk.

I then decide to use water to swim in it but I continue to teleport to the bridge in addition to losing 1/2 heart at each attempt.

you could tell me what kind of problem I'm dealing with and if possible to tell me how to get around it/fix it.
