HI @yos , I gave your GitHub project a try, but it did not transition to the handle error states when my error response from a lambda function contained:

"BookHotelResult": {
  "statusCode": 500,

This error could be because of missing TableName environment variables supplied from process.env.*. Could you check that your Environment Variables are populated? Specifically: github.com/yosriady/serverless-sag...

You can check it from your AWS Lambda console.

hi @yos , I purposely introduced the error, my expectation is that the state machine would have transitioned to the error states, but it instead transitioned to success states.
