Crash give item NBT tag

[splintermik]

Hello, I encountered a bug

when I give myself an object with an NBT tags, it crashes the game ( I test it solo, and no crash)

the typing command is as follows:
/give @A minecraft:diamond_sword{HideFlags:63,CanDestroy:["yellow_flower", "red_flower", "tallgrass", "ladder"]} 1

here's what it says in the logs:

[22:42:42] [Server thread/INFO]: splintermik issued server command: /give @A minecraft:diamond_sword{HideFlags:63,CanDestroy:["yellow_flower", "red_flower", "tallgrass", "ladder"]} 1

Here, I don't know if it's a bug already reported.

thank you :)

After some testing this appears to be a result of 3491f55

Our handling of null items (that can't be found in Minecraft's item namespace) was wrong. Your command references red_flower, tallgrass, and yellow_flower none of which exist.
They're actually poppy, tall_grass, and dandelion respectively.

Paper will now handle these cases better but you should note that your command was probably wrong (unless vanilla MC accepts these and they work, in which case we have some additional item matching to do).

Thanks for letting us know, fixed in builds 326+

I just tested on the server version proposed by mojang

the order does not crash the game on the customer side

but the following tags don't work: yellow_flower, red_flower, tallgrass

thank you very much for the update! :D
