/**
 * 

* The entire transaction request was canceled. *

*

* DynamoDB cancels a TransactWriteItems request under the following circumstances: *

*
    *
  • *

    * A condition in one of the condition expressions is not met. *

    *
  • *
  • *

    * A table in the TransactWriteItems request is in a different account or region. *

    *
  • *
  • *

    * More than one action in the TransactWriteItems operation targets the same item. *

    *
  • *
  • *

    * There is insufficient provisioned capacity for the transaction to be completed. *

    *
  • *
  • *

    * 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. *

    *
  • *
  • *

    * There is a user error, such as an invalid data format. *

    *
  • *
*

* DynamoDB cancels a TransactGetItems request under the following circumstances: *

*
    *
  • *

    * There is an ongoing TransactGetItems operation that conflicts with a concurrent PutItem, * UpdateItem, DeleteItem or TransactWriteItems request. In this case the * TransactGetItems operation fails with a TransactionCanceledException. *

    *
  • *
  • *

    * A table in the TransactGetItems request is in a different account or region. *

    *
  • *
  • *

    * There is insufficient provisioned capacity for the transaction to be completed. *

    *
  • *
  • *

    * There is a user error, such as an invalid data format. *

    *
  • *
* *

* If using Java, DynamoDB lists the cancellation reasons on the CancellationReasons 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 NONE code and Null message. *

*
*

* Cancellation reason codes and possible error messages: *

*
    *
  • *

    * No Errors: *

    *
      *
    • *

      * Code: NONE *
