Custom dispatch errors 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 MultiLocation 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.

Trait Implementations
