By default, the Amazon States Language doesn't set timeouts in state machine definitions. Without an explicit timeout, Step Functions often relies solely on a response from an activity worker to know that a task is complete.
Dashbird continuously monitors and analyses your serverless applications to ensure reliability, cost and performance optimisation and alignment with the Well Architected Framework.
Severity: CRITICAL Resource: AWS::StepFunctions::StateMachine Interval: 1 day Check period: 7 days
One of your state machines doesn’t have a task timeout set.
By default, the Amazon States Language doesn’t set timeouts in state machine definitions. Step Functions often rely solely on an activity worker’s response to know that a task is complete without an explicit timeout. If something goes wrong and TimeoutSeconds isn’t specified, an execution is stuck waiting for a response that will never come.
To avoid this, specify a reasonable timeout when you create a task in your state machine. Read more about configuring timeout limits for Step Functions.
