# NotRootSubnet (/docs/errors/chain/NotRootSubnet)

A call that only operates on the root network, such as setting root network weights, was given a non-root netuid. Check the netuid argument; root operations must target netuid 0.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).

## Remediation [#remediation]

Check the argument values against the operation schema

The same explanation is available in the terminal: `btcli explain NotRootSubnet`.
