How to make entitys spawn in biome without grass

[Azarsra]

So I have a BIome with a custom block has the surface block, But entities do not spawn, I tried using the "valid_spawn.json", but that didn't work. Anyone knows how to fix this?.

So anyone have an Solution? The BIome is working fine and everything else, it is just getting my custom grass to be a valid spawn that is the problem. Also I probably should clarify that hostile mobs spawn, it is just creatures that don't spawn.

Found the problem, Turns out there is a json file called "animals_spawnable_on", and one called "wolves_spawnable_on", And that worked!
