IllegalArgumentException (Cannot set property) when using a block without the "axis" property in fancy_tree_placer

When using a block without the "axis" property in fancy_tree_placer the game crashes when trying to generate the world.

How to reproduce

I added a datapack in the attachments that will cause the issue. I suggest using a single biome world with custom:tall_birch_forest as only biome.

notes:
I haven't verified this but assume a similar issue might occur with the rotated_block_provider
