RootNetUidNotAllowed
Check the argument values against the operation schema
The order or batch targets the root subnet, netuid 0, which the limit orders pallet does not serve. Check the netuid field of the order payload or the netuid parameter of the batch call and target a non-root subnet.
Declared by the LimitOrders pallet; it classifies to the semantic code invalid_argument.
