Expand description
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 concurrentPutItem
,UpdateItem
,DeleteItem
orTransactWriteItems
request. In this case theTransactGetItems
operation fails with aTransactionCanceledException
. -
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
-
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.
This Message is received when provisioned throughput is exceeded is on a provisioned DynamoDB table.
-
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.
This message is returned when provisioned throughput is exceeded is on a provisioned GSI.

-
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: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-partition-key-design.html.
This message is returned when writes get throttled on an On-Demand table as DynamoDB is automatically scaling the table.
-
Throughput exceeds the current capacity for one or more global secondary indexes. DynamoDB is automatically scaling your index so please try again shortly.
This message is returned when when writes get throttled on an On-Demand GSI as DynamoDB is automatically scaling the GSI.

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.
