Custom dispatch errors of this pallet.

Variants

NotController

Not a controller account.

NotStash

Not a stash account.

AlreadyBonded

Stash is already bonded.

AlreadyPaired

Controller is already paired.

EmptyTargets

Targets cannot be empty.

DuplicateIndex

Duplicate index.

InvalidSlashIndex

Slash record index out of bounds.

InsufficientBond

Cannot have a validator or nominator role, with value less than the minimum defined by governance (see MinValidatorBond and MinNominatorBond). If unbonding is the intention, chill first to remove one’s role as validator/nominator.

NoMoreChunks

Can not schedule more unlock chunks.

NoUnlockChunk

Can not rebond without unlocking chunks.

FundedTarget

Attempting to target a stash that still has funds.

InvalidEraToReward

Invalid era to reward.

InvalidNumberOfNominations

Invalid number of nominations.

NotSortedAndUnique

Items are not sorted and unique.

AlreadyClaimed

Rewards for this era have already been claimed for this validator.

IncorrectHistoryDepth

Incorrect previous history depth input provided.

IncorrectSlashingSpans

Incorrect number of slashing spans provided.

BadState

Internal state has become somehow corrupted and the operation cannot continue.

TooManyTargets

Too many nomination targets supplied.

BadTarget

A nomination target was supplied that was blocked or otherwise not a validator.

CannotChillOther

The user has enough bond and thus cannot be chilled forcefully by an external person.

TooManyNominators

There are too many nominators in the system. Governance needs to adjust the staking settings to keep things safe for the runtime.

TooManyValidators

There are too many validator candidates in the system. Governance needs to adjust the staking settings to keep things safe for the runtime.

CommissionTooLow

Commission is too low. Must be at least MinCommission.

BoundNotMet

Some bound is not met.
