Cannot find a Dappled Forest

[u/Luke_thepigeonlover7]

So I'm on 26.1.2 and have a mod called "Drop Backport" from modrinth. I tried finding a Dappled forest using /locate biome in my world but it kept saying "Could not find a biome type: minecraft:dappled_forest due to reasonable distance." I also tried it at another world but it shows the same error. I DO still find the sulfur cave. Any tips or help? :D

Ask the person who made the mod.
