Jets Endpoint URL giving timeout with Deploying Rails application using After Burner

I have followed this link here: https://rubyonjets.com/docs/rails/afterburner/ to include jets on my rails application. After executing jets deploy command it successfully executed and returned me an Endpoint: https://tovnmx1hb9.execute-api.us-east-1.amazonaws.com/dev/users.
After opening this endpoint I am getting the following message:

message: “Endpoint request timed out”

Can you please help me whats wrong going on here ?

Thanks

See:

The first link mentions:

Try going up farther in the CloudWatch logs and see if you can find an error about rackup failing to start. That is the key. Was able to just deploy the tongueroo/demo-rails-api 1 app with Jets Afterburner mode successfully. So, at this point think it’s project specific issue :face_with_monocle: Try to go farther up the CloudWatch logs to find out where rackup is failing to start.

Jets starts the rack server during the cold start for performance. So you have to find the request with the cold start.

Also, just deployed the https://github.com/tongueroo/demo-rails app and it was ok. It may be specific to your setup :face_with_monocle: Would also try spinning up a cloud9 machine and deploying the demo-app from there. That may help eliminate specific setup issues.

I have checked the logs but found no errors in the logs. Here are the full details of my approach.

basically I have an application and was getting the timeout message in the browser after hitting the API URl. Then I tried it with your demo-rails app to see if it works or not. It does not work either and getting the same timeout message.

Full Code can be seen here. I hjust have used Postgresql and different rails version

Please have a view on my below Gemfile, Gemfil.lock, Api URL and cloudwatch Logs and assist me what I am doing wrong here.

In the logs I can only see that the Jets::RackController#process got timedout after 30 seconds. Please see the below logs
