CanNotSetRootNetworkWeights

set_weights was called with netuid 0, the root network, where normal weight setting is not allowed. Use a non-root netuid argument; root weights are handled by a separate mechanism.

Declared by the SubtensorModule pallet; it classifies to the semantic code invalid_argument.

Declared at pallets/subtensor/src/macros/errors.rs#L117.
