InvalidIpType
Check the argument values against the operation schema
The ip_type argument to serve_axon or serve_prometheus is not 4 or 6. Check the value being sent by the miner or client; only IPv4 (4) and IPv6 (6) are accepted.
Declared by the SubtensorModule pallet; it classifies to the semantic code invalid_argument.
Remediation
