submit_job = tasks.LambdaInvoke(self, "Invoke Handler",

    payload=sfn.TaskInput.from_json_path_at("$.input"),
    invocation_type=tasks.LambdaInvocationType.EVENT

Attributes

DRY_RUN: Validate parameter values and verify that the user or role has permission to invoke the function.

EVENT

Invoke the function asynchronously.

Send events that fail multiple times to the function’s dead-letter queue (if it’s configured). The API response only includes a status code.

REQUEST_RESPONSE

Invoke the function synchronously.

Keep the connection open until the function returns a response or times out. The API response includes the function response and additional data.
