When connecting to my BDS I don't get any request to download a resource pack, which is in the resource_packs folder. valid_known_packs.json shows the resource pack. Setting the texturepack-required=true in the server.properties doesn't have any effect. In version 1.19.81.01 everything was working fine.
Edit: The resource pack is working on my realm as expected
I'm sorry, the problem wasn't the BDS. I completely forgot to update the world_resource_packs.json in the world folder. Now everything is working as expected.
Cheers
