/**
 * <p>
 * The entire transaction request was canceled.

 * <p>
 * DynamoDB cancels a <code>TransactWriteItems</code> request under the following circumstances:
 * </p>
 * <ul>
 * <li>
 * <p>
 * A condition in one of the condition expressions is not met.
 * </p>
 * </li>
 * <li>
 * <p>
 * A table in the <code>TransactWriteItems</code> request is in a different account or region.
 * </p>
 * </li>
 * <li>
 * <p>
 * More than one action in the <code>TransactWriteItems</code> operation targets the same item.
 * </p>
 * </li>
 * <li>
 * <p>
 * There is insufficient provisioned capacity for the transaction to be completed.
 * </p>
 * </li>
 * <li>
 * <p>
 * An item size becomes too large (larger than 400 KB), or a local secondary index (LSI) becomes too large, or a similar
 * validation error occurs because of changes made by the transaction.
 * </p>
 * </li>
 * <li>
 * <p>
 * There is a user error, such as an invalid data format.
 * </p>
 * </li>
 * </ul>
 * <p>
 * DynamoDB cancels a <code>TransactGetItems</code> request under the following circumstances:
 * </p>
 * <ul>
 * <li>
 * <p>
 * There is an ongoing <code>TransactGetItems</code> operation that conflicts with a concurrent <code>PutItem</code>,
 * <code>UpdateItem</code>, <code>DeleteItem</code> or <code>TransactWriteItems</code> request. In this case the
 * <code>TransactGetItems</code> operation fails with a <code>TransactionCanceledException</code>.
 * </p>
 * </li>
 * <li>
 * <p>
 * A table in the <code>TransactGetItems</code> request is in a different account or region.
 * </p>
 * </li>
 * <li>
 * <p>
 * There is insufficient provisioned capacity for the transaction to be completed.
 * </p>

 * <li>
 * <p>
 * There is a user error, such as an invalid data format.
 * </p>
 * </li>
 * </ul>
 * <note>
 * <p>
 * If using Java, DynamoDB lists the cancellation reasons on the <code>CancellationReasons</code> property. This
 * property is not set for other languages. Transaction cancellation reasons are ordered in the order of requested
 * items, if an item has no error it will have <code>None</code> code and <code>Null</code> message.
