No known_valid_packs.json present, resource pack not working

[abhemanyus]

I've been trying to install several crafting tweaks from bedrocktweaks.
Even after following all the steps specified in the docs, the pack is not installed properly and does not work.
From what I've seen in other tutorials, there should be a known_valid_packs.json in the data directory, that gets updated whenever a new directory is created within /data/resource_packs or /data/behavior_packs. However, no such file exists.

Minecraft Bedrock version: 1.21.31.04
docker-minecraft-bedrock-server version: latest (28e90626f0e4)
Resource pack: better crafting.zip

Anyone knows how to install any kind of custom content in the container?
