NotControllerNot a controller account.
NotStashNot a stash account.
AlreadyBondedStash is already bonded.
AlreadyPairedController is already paired.
EmptyTargetsTargets cannot be empty.
DuplicateIndexDuplicate index.
InvalidSlashIndexSlash record index out of bounds.
InsufficientBondCannot have a validator or nominator role, with value less than the minimum defined bygovernance (see `MinValidatorBond` and `MinNominatorBond`). If unbonding is theintention, `chill` first to remove one's role as validator/nominator.
NoMoreChunksCan not schedule more unlock chunks.
NoUnlockChunkCan not rebond without unlocking chunks.
FundedTargetAttempting to target a stash that still has funds.
InvalidEraToRewardInvalid era to reward.
InvalidNumberOfNominationsInvalid number of nominations.
NotSortedAndUniqueItems are not sorted and unique.
AlreadyClaimedRewards for this era have already been claimed for this validator.
InvalidPageNo nominators exist on this page.
IncorrectHistoryDepthIncorrect previous history depth input provided.
IncorrectSlashingSpansIncorrect number of slashing spans provided.
BadStateInternal state has become somehow corrupted and the operation cannot continue.
TooManyTargetsToo many nomination targets supplied.
BadTargetA nomination target was supplied that was blocked or otherwise not a validator.
CannotChillOtherThe user has enough bond and thus cannot be chilled forcefully by an external person.
TooManyNominatorsThere are too many nominators in the system. Governance needs to adjust the stakingsettings to keep things safe for the runtime.
TooManyValidatorsThere are too many validator candidates in the system. Governance needs to adjust thestaking settings to keep things safe for the runtime.
CommissionTooLowCommission is too low. Must be at least `MinCommission`.
BoundNotMetSome bound is not met.
ControllerDeprecatedUsed when attempting to use deprecated controller account logic.
CannotRestoreLedgerCannot reset a ledger.
RewardDestinationRestrictedProvided reward destination is not allowed.
NotEnoughFundsNot enough funds available to withdraw.
VirtualStakerNotAllowedOperation not allowed for virtual stakers.
CannotReapStashStash could not be reaped as other pallet might depend on it.
AlreadyMigratedThe stake of this account is already migrated to `Fungible` holds.
RestrictedAccount is restricted from participation in staking. This may happen if the account isstaking in another way already, such as via pool.
