Just change the version of Mongoose to the latest release:
"mongoose": "4.2.7"
run "npm install" again followed by "node generateData.js"

Should be resolved now

Had the same issue. Even with no restrictions on other modules and updated versions, limiting the mongoose version to 4.2.7 seems to do the trick.
