# RevealPeriodTooLarge (/docs/errors/chain/RevealPeriodTooLarge)

`set_reveal_period` was given a commit-reveal period above the compiled-in maximum number of epochs. Lower the `reveal_period` argument; the current setting is readable from `RevealPeriodEpochs` for the netuid.

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