Filing cabinet doesn't drop items

[Phoupraw]

I filled 3 filing cabinets with lots of enchanted books, bows and fishing rods. After I broke them, they didn't drop anything, and at the same time, the following log was printed.

[Server thread/ERROR]: Failed to handle packet net.minecraft.class_2846@774f8807, suppressing error
