The Error enum of this pallet.

Variants

Unreachable

The desired destination was unreachable, generally because there is a no way of routing to it.

SendFailure

There was some other issue (i.e. not to do with routing) in sending the message. Perhaps a lack of space for buffering the message.

Filtered

The message execution fails the filter.

UnweighableMessage

The message’s weight could not be determined.

DestinationNotInvertible

The destination Location provided cannot be inverted.

Empty

The assets to be sent are empty.

CannotReanchor

Could not re-anchor the assets to declare the fees for the destination chain.

TooManyAssets

Too many assets have been attempted for transfer.

InvalidOrigin

Origin is invalid for sending.

BadVersion

The version of the Versioned value used is not able to be interpreted.

BadLocation

The given location could not be used (e.g. because it cannot be expressed in the desired version of XCM).

NoSubscription

The referenced subscription could not be found.

AlreadySubscribed

The location is invalid since it already has a subscription from us.

CannotCheckOutTeleport

Could not check-out the assets for teleportation to the destination chain.

LowBalance

The owner does not own (all) of the asset that they wish to do the operation on.

TooManyLocks

The asset owner has too many locks on the asset.

AccountNotSovereign

The given account is not an identifiable sovereign account for any location.

FeesNotMet

The operation required fees to be paid which the initiator could not meet.

LockNotFound

A remote lock with the corresponding data could not be found.

InUse

The unlock operation cannot succeed because there are still consumers of the lock.

InvalidAssetUnknownReserve

Invalid asset, reserve chain could not be determined for it.

InvalidAssetUnsupportedReserve

Invalid asset, do not support remote asset reserves with different fees reserves.

TooManyReserves

Too many assets with different reserve locations have been attempted for transfer.

LocalExecutionIncomplete

Local XCM execution incomplete.
