You can configure Step Functions to catch the error using a Catch rule: { "StartAt": "CreateAccount", "States": { "CreateAccount": { "Type": "Task", "Resource": "arn:aws:lambda:us-east-1:123456789012:function:CreateAccount",
"Resource": "arn:aws:lambda:us-east-1:xxxx:function:LabStack-prewarm-b286746e-ModelCompleteNotificatio-M3NuGqTesrCg", "End": true, "Catch": [ { "ErrorEquals": [ "States.ALL" ], "Next": "ErrorState", "ResultPath": "$.output.error" ...
According to the AWS Step Functions documentation and the error message, when using ResultWriter with JSONata, the ASL should include an "Arguments" field like this: "ResultWriter": { "Resource": "arn:aws:states:::s3:putObject", "Arguments": { ...
