Hey vaibhav chawla,
Please make sure you must have
start script in your
package.json file. In order to start your node app, Dokku will run
npm start so please make sure you must have it.
If you are still getting issues with it. You can log on to your server where you deployed the application and use
dokku logs yourappname -t to get logs of the application and you can see there what’s the error.
Thanks for responding, if you still got issues please feel free to mail me at firstname.lastname@example.org
Have a great day ahead!
