Properties for StartExecution.

Example

// Define a state machine with one Pass state
const child = new sfn.StateMachine(this, 'ChildStateMachine', {
  definition: sfn.Chain.start(new sfn.Pass(this, 'PassState')),
});

// Include the state machine in a Task state with callback pattern
const task = new tasks.StepFunctionsStartExecution(this, 'ChildTask', {
  stateMachine: child,
  integrationPattern: sfn.IntegrationPattern.WAIT_FOR_TASK_TOKEN,
  input: sfn.TaskInput.fromObject({
    token: sfn.JsonPath.taskToken,
    foo: 'bar',
  }),
  name: 'MyExecutionName',
});

// Define a second state machine with the Task state above
new sfn.StateMachine(this, 'ParentStateMachine', {
  definition: task,
});

stateMachine

Type: IStateMachine

The Step Functions state machine to start the execution on.


associateWithParent?

Type: boolean (optional, default: false)

Pass the execution ID from the context object to the execution input.

This allows the Step Functions UI to link child executions from parent executions, making it easier to trace execution flow across state machines.

If you set this property to true, the input property must be an object (provided by sfn.TaskInput.fromObject) or omitted entirely.

comment?

Type: string (optional, default: No comment)

An optional description for this state.


credentials?

Type: Credentials (optional, default: None (Task is executed using the State Machine's execution role))

Credentials for an IAM Role that the State Machine assumes for executing the task.

This enables cross-account resource invocations.

heartbeat?⚠️

⚠️ Deprecated: use heartbeatTimeout

Type: Duration (optional, default: None)

Timeout for the heartbeat.


heartbeatTimeout?

Type: Timeout (optional, default: None)

Timeout for the heartbeat.

[disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface


input?

Type: TaskInput (optional, default: The state input (JSON path '$'))

The JSON input for the execution, same as that of StartExecution.

See also: https://docs.aws.amazon.com/step-functions/latest/apireference/API_StartExecution.html


inputPath?

Type: string (optional, default: The entire task input (JSON path '$'))

JSONPath expression to select part of the state to be the input to this state.

May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}.


integrationPattern?

Type: IntegrationPattern (optional, default: IntegrationPattern.REQUEST_RESPONSE for most tasks. IntegrationPattern.RUN_JOB for the following exceptions: BatchSubmitJob, EmrAddStep, EmrCreateCluster, EmrTerminationCluster, and EmrContainersStartJobRun.)

AWS Step Functions integrates with services directly in the Amazon States Language.

You can control these AWS services using service integration patterns

name?

Type: string (optional, default: None)

The name of the execution, same as that of StartExecution.

See also: https://docs.aws.amazon.com/step-functions/latest/apireference/API_StartExecution.html


outputPath?

Type: string (optional, default: The entire JSON node determined by the state input, the task result, and resultPath is passed to the next state (JSON path '$'))

JSONPath expression to select select a portion of the state output to pass to the next state.

May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}.


resultPath?

Type: string (optional, default: Replaces the entire input with the result (JSON path '$'))

JSONPath expression to indicate where to inject the state's output.

May also be the special value JsonPath.DISCARD, which will cause the state's input to become its output.


resultSelector?

Type: { [string]: any } (optional, default: None)

The JSON that will replace the state's raw result and become the effective result before ResultPath is applied.

You can use ResultSelector to create a payload with values that are static or selected from the state's raw result.

taskTimeout?

Type: Timeout (optional, default: None)

Timeout for the task.

[disable-awslint:duration-prop-type] is needed because all props interface in aws-stepfunctions-tasks extend this interface


timeout?⚠️

⚠️ Deprecated: use taskTimeout

Type: Duration (optional, default: None)

Timeout for the task.
