Trying to set or fill a block with a certain property with the "run_command" feature inside of events, completely breaks the mob

So basically, when trying to run the command "execute as @s at @s run setblock ~~~1 planks["wood_type": "dark_oak"]" doesn't work inside of an entity, or inside of server animations. No matter what I do, this method doesn't seem to be working whatsoever, it just completely breaks. However, whenever I remove the option to set the block with a certain property, it seems to work just fine.

 

And I do have a suggestion, for a fix, instead of just doing setblock ~~~ planks["wood_type": "dark_oak"] maybe you could add the option to do setblock ~~~ planks['wood_type': 'dark_oak'] instead.
