问题 My state in a step function flow returns an error of state/task returned a result with a size exceeding the maximum number of characters service limit. . In the step function documentation, the limit for characters for input/output is 32,768 characters . Upon checking the total characters of my result data if falls below the limit. Are there any other scenarios that it will throw that error? Thanks! 回答1: 32KB is the maximum size of the payload that can be passed between states. You could also

问题 Currently I have a use case that a cloud watch rule will trigger a step function every 5 minutes. I want to have a logic to skip starting another execution if there is one execution already running in step function. Any way to do that? 回答1: Instead of having your CloudWatch event rule trigger the Step Function directly, you could have it trigger a Lambda function. The Lambda function could check if there are any Step Function executions in the RUNNING state, via the ListExecutions API. If not

问题 Im creating a POC with nested Step Functions (SF) and have hit the following issue. I have SF A that has a sync task that starts the execution of SF B (using the recently announced syntax) & waits for it to complete. SF B returns a valid JSON output In SF A, I can see (from the output of the task that calls SF B) the correct fields returned. e.g Status, ExecutionArn as well as the Output. I then want to execute a Choice Task in SF A that uses a field returned from SF B. However the json in

问题 I'm working on AWS Step functions. I've read the documentation on InputPath, OutputPath, and ResultPath. My problem is that I want to combine values from the input to a Lambda Task with a partial output from the task. The input to the task is similar to below. I want to continue passing these values on to subsequent tasks. { "previous_task_result": 100, "next_task_input": "asdf" } What I would like, is to have the output of my Lambda Task look like this: { "previous_task_result": 100, "next

问题 I am getting the following error when I try to create a state machine based on my state machine definition: botocore.exceptions.ClientError: An error occurred (AccessDeniedException) when calling the CreateStateMachine operation: 'role' is not authorized to create managed-rule. The creation code: state_machine = sfn_client.create_state_machine( name = 'state-machine', definition = state_machine_def, roleArn = SFN_ROLE, ) My IAM role that I use contains all necessary permissions as described
