Deeper darker spawning issue

[XeeXeeVR]

As for any other nether-like dimension it spawns me on top of the bedrock roof of the deeper and darker dimension. I'm aware of the method of excluding dimensions however I can't seem to find the exact tag to add for the deeper darker dimension. This is on forge 1.20.1 but I do see a number of people having the same issue all over the place

I don't know anything about modding but if possible a solution could be to not allow the teleport to put you on bedrock that is above sea level or something along those lines. So say the bedrock is 150 blocks up in the world the game registers it as a bedrock roof and finds a place below it that won't suffocate you and places you there instead
