Server failed to send packet resource_packs_info: SizeOf error for undefined : Cannot read properties of undefined (reading 'length')

[TheChuan1503]

This issue exists in both bedrock-protocol@3.47.0 and the latest 3.52.0.

• System: Windows 11 25H2 26200.7623
• NodeJS: v22.16.0
• bedrock-protocol: v3.47.0 or v3.52.0
• bedrock-protocol Server: 1.20.80
• Minecraft: 1.20.81.01 (Windows, Logged In)

Codes

bedrock.createServer({
    host: '127.0.0.1',
    port: 19132,
    offline: true
}).on('connect', client => {
    client.on('packet', p => {
        switch (p.data.name) {
            case 'client_cache_status': {
                client.queue('resource_packs_info', {"must_accept":false,"has_addons":false,"has_scripts":false,"world_template":{"uuid":"00000000-0000-0000-0000-000000000000","version":"0.0.0"},"texture_packs":[]})
                break
            }
        }
    })
})

I remember this code used to seem to work correctly.
But now even sending standard data packets can cause a crash.

{"must_accept":false,"has_addons":false,"has_scripts":false,"force_server_packs":false,"behaviour_packs":[],"texture_packs":[],"resource_pack_links":[]}
