I noticed these error messages in my server log. The log is attached. There was no crash, the playing process was smooth.

I've gotten this error while pre-generating chunks in a world, so can confirm it happens :)

Can confirm it, happend also several times while pre generating a 10000 squared block world.
For 10000² blocks only 20 times "[Paper Async Chunk Task Thread #0/ERROR]: Unknown tag: minecraft:doors" in a world with type normal. So I have no clue in witch kind of structure it might happen, since only 20 times.

Any update on this? It too happened to me and I'm wondering whether a village bugged during generation and generated without doors.

Happened to me just after restarting my server.

Mojang removed some features from the game but didn't pull their data during upgrades, this is essentially harmless albeit annoying
