POST failing when running json server via npm run

I have json server configured to run conveniently using a npm-run-script like so npm run db.

{
  "name": "My App",
  "scripts": {
    "db": "json-server --watch db.json --port 3004"
  }
}

This works fine for all GET requests, however, fails for any POST request with the following stacktrace:

TypeError: _.maxBy is not a function

This is not a problem if I was to run the json-server command manually on the command line using the very same db.json that I have.

Seems like there is a problem with the scope that is used to run the script?
