Overview

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.
There is an ongoing ‘TransactWriteItems` operation that conflicts with a concurrent `TransactWriteItems` request. In this case the `TransactWriteItems` operation fails with a `TransactionCanceledException`.

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.

<note markdown=“1”> 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.

</note>

Cancellation reason codes and possible error messages:

No Errors:
- Code: ‘None`
- Message: ‘null`
Conditional Check Failed:
- Code: ‘ConditionalCheckFailed`
- Message: The conditional request failed.
Item Collection Size Limit Exceeded:
- Code: ‘ItemCollectionSizeLimitExceeded`
- Message: Collection size exceeded.
Transaction Conflict:
- Code: ‘TransactionConflict`
- Message: Transaction is ongoing for the item.
Provisioned Throughput Exceeded:
- Code: ‘ProvisionedThroughputExceeded`
- Messages:
  - The level of configured provisioned throughput for the table was exceeded. Consider increasing your provisioning level with the UpdateTable API.
    
    <note markdown=“1”> This Message is received when provisioned throughput is exceeded is on a provisioned DynamoDB table.
```
</note>
```
  - The level of configured provisioned throughput for one or more global secondary indexes of the table was exceeded. Consider increasing your provisioning level for the under-provisioned global secondary indexes with the UpdateTable API.
    
    <note markdown=“1”> This message is returned when provisioned throughput is exceeded is on a provisioned GSI.
```
</note>
```
Throttling Error:
- Code: ‘ThrottlingError`
- Messages:
  - Throughput exceeds the current capacity of your table or index. DynamoDB is automatically scaling your table or index so please try again shortly. If exceptions persist, check if you have a hot key: docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-partition-key-design.html.
    
    <note markdown=“1”> This message is returned when writes get throttled on an On-Demand table as DynamoDB is automatically scaling the table.

Validation Error:
- Code: ‘ValidationError`
- Messages:
  - One or more parameter values were invalid.
  - The update expression attempted to update the secondary index key beyond allowed size limits.
  - The update expression attempted to update the secondary index key to unsupported type.
  - An operand in the update expression has an incorrect data type.
  - Item size to update has exceeded the maximum allowed size.
  - Number overflow. Attempting to store a number with magnitude larger than supported range.
  - Type mismatch for attribute to update.
  - Nesting Levels have exceeded supported limits.
  - The document path provided in the update expression is invalid for update.
  - The provided expression refers to an attribute that does not exist in the item.
