generate-keys script errors out

[agerbens]

I get an ERR_INVALID_CALLBACK error after running npm run generate-keys inside the api container:

/src/api# npm run generate-keys

> [email protected] generate-keys /src/api
> node src/bin/generate-keys.js

info: Generating keys. This will take a few seconds...
fs.js:129
  throw new ERR_INVALID_CALLBACK();
  ^

TypeError [ERR_INVALID_CALLBACK]: Callback must be a function
    at maybeCallback (fs.js:129:9)
    at Object.write (fs.js:536:14)
    at fs.open (/src/api/src/bin/generate-keys.js:44:8)
    at FSReqWrap.oncomplete (fs.js:141:20)

Seems like it wants a callback passed in as the 3rd argument to fs.write in that script. Something like:

fs.write(fd, JSON.stringify(keystores), function(err, result) {
  if(err) console.log('error', err);
});
