Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ActivityAlreadyExists(ActivityAlreadyExists)

Activity already exists. EncryptionConfiguration may not be updated.

ActivityDoesNotExist(ActivityDoesNotExist)

The specified activity does not exist.

ActivityLimitExceeded(ActivityLimitExceeded)

The maximum number of activities has been reached. Existing activities must be deleted before a new activity can be created.

ActivityWorkerLimitExceeded(ActivityWorkerLimitExceeded)

The maximum number of workers concurrently polling for activity tasks has been reached.

ConflictException(ConflictException)

Updating or deleting a resource can cause an inconsistent state. This error occurs when there're concurrent requests for DeleteStateMachineVersion, PublishStateMachineVersion, or UpdateStateMachine with the publish parameter set to true.

HTTP Status Code: 409

ExecutionAlreadyExists(ExecutionAlreadyExists)

The execution has the same name as another execution (but a different input).

Executions with the same name and input are considered idempotent.

ExecutionDoesNotExist(ExecutionDoesNotExist)

The specified execution does not exist.

ExecutionLimitExceeded(ExecutionLimitExceeded)

The maximum number of running executions has been reached. Running executions must end or be stopped before a new execution can be started.

ExecutionNotRedrivable(ExecutionNotRedrivable)

The execution Amazon Resource Name (ARN) that you specified for executionArn cannot be redriven.

InvalidArn(InvalidArn)

The provided Amazon Resource Name (ARN) is not valid.

InvalidDefinition(InvalidDefinition)

The provided Amazon States Language definition is not valid.

InvalidEncryptionConfiguration(InvalidEncryptionConfiguration)

Received when encryptionConfiguration is specified but various conditions exist which make the configuration invalid. For example, if type is set to CUSTOMER_MANAGED_KMS_KEY, but kmsKeyId is null, or kmsDataKeyReusePeriodSeconds is not between 60 and 900, or the KMS key is not symmetric or inactive.

InvalidExecutionInput(InvalidExecutionInput)

The provided JSON input data is not valid.

InvalidLoggingConfiguration(InvalidLoggingConfiguration)

Configuration is not valid.

InvalidName(InvalidName)

The provided name is not valid.

InvalidOutput(InvalidOutput)

The provided JSON output data is not valid.

InvalidToken(InvalidToken)

The provided token is not valid.

InvalidTracingConfiguration(InvalidTracingConfiguration)

Your tracingConfiguration key does not match, or enabled has not been set to true or false.

KmsAccessDeniedException(KmsAccessDeniedException)

Either your KMS key policy or API caller does not have the required permissions.

KmsInvalidStateException(KmsInvalidStateException)

The KMS key is not in valid state, for example: Disabled or Deleted.

KmsThrottlingException(KmsThrottlingException)

Received when KMS returns ThrottlingException for a KMS call that Step Functions makes on behalf of the caller.

MissingRequiredParameter(MissingRequiredParameter)

Request is missing a required parameter. This error occurs if both definition and roleArn are not specified.

ResourceNotFound(ResourceNotFound)

Could not find the referenced resource.

ServiceQuotaExceededException(ServiceQuotaExceededException)

The request would cause a service quota to be exceeded.

HTTP Status Code: 402

StateMachineAlreadyExists(StateMachineAlreadyExists)

A state machine with the same name but a different definition or role ARN already exists.

StateMachineDeleting(StateMachineDeleting)

The specified state machine is being deleted.

StateMachineDoesNotExist(StateMachineDoesNotExist)

The specified state machine does not exist.

StateMachineLimitExceeded(StateMachineLimitExceeded)

The maximum number of state machines has been reached. Existing state machines must be deleted before a new state machine can be created.

StateMachineTypeNotSupported(StateMachineTypeNotSupported)

State machine type is not supported.

TaskDoesNotExist(TaskDoesNotExist)

The activity does not exist.

TaskTimedOut(TaskTimedOut)

The task token has either expired or the task associated with the token has already been closed.

TooManyTags(TooManyTags)

You've exceeded the number of tags allowed for a resource. See the Limits Topic in the Step Functions Developer Guide.

ValidationException(ValidationException)

The input does not satisfy the constraints specified by an Amazon Web Services service.

Unhandled(Unhandled)

👎Deprecated: Matching Unhandled directly is not forwards compatible. Instead, match using a variable wildcard pattern and check .code():    err if err.code() == Some("SpecificExceptionCode") => { /* handle the error */ } See ProvideErrorMetadata for what information is available for the error.

An unexpected error occurred (e.g., invalid JSON returned by the service or an unknown error code).
