Title: Vector Search with JavaScript
I have cloned the git repo from GitHub - hummusonrails/vector-example-blog-platform: Fully featured Medium.com clone with vector search functionality.

Unfortunately, I can not start it (on main branch):

> npm install; npm run dev
...
/Users/markus/git/vector-example-blog-platform/models/User.js:57
userModel.methods.generateAccessToken = function() {
                                      ^

TypeError: Cannot set properties of undefined (setting 'generateAccessToken')

Node.js v20.17.0
[nodemon] app crashed - waiting for file changes before starting...

Also: what version of Couchbase should I install? Is the community edition sufficient?

Thanks
