1.20.2 and 1.20.3 missing metadataKeys in entities.json.

Seems that the minecraft-data-generator-server doesn't output that information, and the tests don't check that it exists.

I will look into getting this information into the entities.json on both versions and look into if minecraft-data-generator-server can generate it.

Also just looked and Burger also does not extract this info, so it might be manual.

You can look at git blame info to find the commit that added it previously

#710 info on how to extract
Would be good to automate that

Yeah, looks like it was not added to the doc. Running the extraction script in tools/js will generate it. The reason there is no test is that it's technically optional, as we don't have the data for all the versions. I guess a test could be done to check if versions newer than X have the field, but maybe the better solution would be to try and get all the data back.

Personally I dont see as technically optional when mineflayer requires it to pass all its tests on current versions. I am looking into adding support in minecraft-data-generator-server.

[extremeheat]

mineflayer is independent to minecraft-data, so what's optional in minecraft-data may indeed not be optional for mineflayer

Adding more data validation and in general data quality tests to Minecraft data would definitely help.
It can be done as a failing test but it can also be implemented as a report that is sent by a bot.

See PrismarineJS/prismarine-packet-dumper#82 (comment) as an example of what a quality report might look like
