# BlockDurationTooShort (/docs/errors/chain/BlockDurationTooShort)

The requested `end` block is fewer than `MinimumBlockDuration` blocks after the current block. Compare `end` minus the current block number against the `MinimumBlockDuration` pallet constant when calling `create` or `update_end`.

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