Error while running docker-compose.dev.yml locally to develop node app

[mudabir94]

I am following the language specific guides for node.js and stuck on "develop your app" section.
Everything runs smoothly as instructed until "use compose to develop locally"
I have copied the code into the docker-compose.dev.yml file into my project and run this command

** docker-compose -f docker-compose.dev.yml up --build ** which doesn't run nodemon and gives me the following error.

"""

All packages are installed and updated the package.json file to enable the debug mode.

It have been resolved. The problem was in server.js file.
The code given in the tutorial for server.js file is not complete. It is missing the catch required to handle the promising. This should be updated.

https://github.com/rumpl/memphis/blob/main/notes-service/server.js

This repo has given the code and idea how to write the server.js file code.
I've tweaked the server.js code to make it simple and according to the tutorial given.

async function main() {

try {
await database.connect( process.env.CONNECTIONSTRING )

const server = ronin.server({
		port: process.env.SERVER_PORT
	})

	server.use( '/', mocks.server( server.Router()) )
	

const result = await server.start()
	console.info( result )

} catch( error ) {
	console.error( error )
}

}

Thank you.
