Non-vanilla core shaders are not rendered

I create a custom core shader, which essentially copies the vanilla end gateway shader, but adds a third texture, which is used as an alpha mask. This causes an error in the game log and prevents the shader to be displayed:

[20:15:28] [Render thread/ERROR]: Missing program minecraft:core/elytratrims_gateway in override list. This is not a critical problem, but it could lead to weird rendering.
