Main entry point does not exist
If you get an error in the deploy log that says that your
package.json points to a file that does not exist, here is how to fix.
ERROR: The main entry point defined in package.json 'index.js' does not exist.
To fix do the following:
- update the entry in package.json that points to the correct file:
Cyclic launches your code by running

main entry in your
package.json. If that entry does not exist it will then default to
Either you can define a

Or, you can ensure the entry point to your Express application is a
server.js file in the root directory.
Why does this happen?
By default when you run
npm init it creates a
main entry in
package.json which points to
index.js. Most frameworks init their entry points in files other than
index.js in the root directory. Hence the mismatch in default behavior.
