# SubnetDoesNotExist (/docs/errors/chain/SubnetDoesNotExist)

The admin-utils call targets a netuid with no registered subnet. Verify the `netuid` argument against `NetworksAdded` (the set of existing subnets) before setting hyperparameters.

Declared by the `AdminUtils` pallet; it classifies to the semantic code [`subnet_not_exists`](/docs/errors/subnet-not-exists).

## Remediation [#remediation]

Use an existing netuid; `btcli subnets list` shows valid ones

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