sip create dispatch rule 'missing rule'

[rashad-leapai]

Hi, I have a self-hosted LiveKit server and SIP server. I created the SIP trunk successfully, but I am getting a 'missing rule' error when I try to create a dispatch rule. I am not sure what I am missing.

lk sip dispatch create
--api-key --api-secret
--url wss://livekit.domain.com sip_dispatch.json

where sip_dispatch.json as:
{ "name": "Demo Dispatch Rule", "rule": { "dispatchRuleIndividual": { "roomPrefix": "call-" } }, "roomConfig": { "agents": [{ "agentName": "agent-name" }] }, "trunk_ids": ["ST_hLaTV76BNRHS"] }

Error is: missing rule
lk version 2.4.10
