i am using dimensional doors for minecraft 1.7.10, i was just hoping someone might know why it says "Dungeon generation failed unexpectedly" whenever i try to test my custom rooms. it doesnt matter what is in the room, or what they are named. it succeeds at exporting, then wont let me test it at all.

google shows nothing for "dungeon generation failed unexpectedly", even without the minecraft tag, so really hoping someone here can help as a last resort.....

Wait. You are having trouble creating new dungeon stuff. We don't support 1.7.10. If you are using dimensional doors by itself, the fabric 1.17 version is recommended. Great care has been made in ensuring most old schematic ported safely throughout the versions (redstone was a mess to port). It also features a fully decked datapack support for custom dungeons which if I'm reading correctly is what you want.
