```

Allows recalling a transfer that was sent to a non-existing account and was not used
to create the account.

Must be signed by an auth descriptor with `accounts.auth_flags.TRANSFER`

Throws if recalling is impossible. Common cases include:

* account registration on transfer is not allowed
* some conditions added in development through recall\_on\_internal\_transfer extensions
  (`recall_on_internal_transfer`) aren't met

**Parameters**

* **transfer\_tx\_rid** — the rid of the transfer which contains the original transfer. Can be fetched e.g., by using `crosschain.get_pending_transfers_for_account`
* **transfer\_op\_index** — the index of the transfer operation inside the transaction referred to by the `transfer_tx_rid` parameter.
