error occurs when run "api-example"

Message: seneca: Ready function failed: this.make$ is not a function

[giannifiore]

Solved with: npm-install seneca-entity and adding an use instruction:

var seneca = require('seneca')()
    .use('entity')
    .use('./product_catalog')
    .use('./api')
    .ready(function (){
        this.make$('product')
        .make$({ id$: 0, name: 'Apple', price: 99, star: 0 }).save$()
        .make$({ id$: 1, name: 'Orange', price: 199, star: 0 }).save$()
})

But then you fall into this other issue, like it happened to me: #37
This other seems related to seneca version
