Frontend + Serverless app hybrid

Hi,
Platform version → 2.3
I have a freshdesk front end which is working fine from locations cti_global_sidebar, ticket_sidebar and ticket_background.
Now i want to configure serverless events in the same app code, but it is not working, below is my manifest.json and folder structure

And below is my server.js file

Below is fdk run command logs

and when i try to access http://localhost:10001/web/test
it shows “This app does not have a serverless component.”

I dont see any errors anywhere else . What am I missing ?

My main requirement is to track any changes on a particular ticket
I am able to intercept the ticket properties change using ticket.propertiesUpdated in Frontend app
I am also able to detect that a new note has been added to that ticket using ticket.addNote event in Frontend app
But I am not able to intercept Note updation and Note deletion, so need a solution to intercept these 2 events!
