# RootWeightCapExceeded (/docs/errors/chain/RootWeightCapExceeded)

Retired (kept for SCALE index stability on the 463 testnet/devnet runtime): one destination in a `set_root_weights` vector exceeded `RootWeightsCap`. That call is gone; the live guard is `BasketConcentrationCapExceeded` on `swap_basket`.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`limit_exceeded`](/docs/errors/limit-exceeded).

Declared at [`pallets/subtensor/src/macros/errors.rs#L371`](/code/pallets/subtensor/src/macros/errors.rs#L371).

## Remediation [#remediation]

A chain-side capacity limit was hit; reduce the size or count of the request

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