public class LambdaInvoke
extends TaskStateBase

Invoke a Lambda function as a Task.

Example:

 Function fn;
 LambdaInvoke.Builder.create(this, "Invoke with callback")
         .lambdaFunction(fn)
         .integrationPattern(IntegrationPattern.WAIT_FOR_TASK_TOKEN)
         .payload(TaskInput.fromObject(Map.of(
                 "token", JsonPath.getTaskToken(),
                 "input", JsonPath.stringAt("$.someField"))))
         .build();
