Custom handler for postsPage not working... Why?

I need to create a custom handler to fetch info from my custom WP-REST api endpoint. I have done this before. Actually, this worked, but as soon as I changed the pattern to “/blog” (so info would be added to postsPage), the handler isn’t being even evaluated. I have tried changing the priority and the pattern. I’m logging the data received, and it seems to me everything is on its place but handler still not working.

I created a brand new project with the necessary code for evaluation. Here is the repository url:

Here you can see snippets of the code:

/src/handlers/categories.js, where I export the handler. Console.log is never fired.

const categories = {
    name: 'categories',

    priority: 10,

    pattern: '/blog',

    func: async ({link, libraries, state}) => {
        console.log('Being handled') /*I should see this on console*/
        const response = await libraries.source.api.get({
            endpoint: '/jasonsegnini/v1/categories/'

        const categories = await response.json()

        Object.assign([link], {
           categories: categories

export default categories

The index.js:

import Root from "./components"
import categories from "./handlers/categories"

const myFirstTheme = {
  name: "test-theme",
  roots: {
    theme: Root,
  state: {
    theme: {},
  actions: {
    theme: {
      init: ({libraries}) =>

      beforeSSR: async ({state, actions}) =>
        await actions.source.fetch(state.source.postsPage) /*postsPage is /blog, same as the handler's pattern*/

export default myFirstTheme

The theme settings:

const settings = {
  "name": "test-project",
  "state": {
    "frontity": {
      "url": "",
      "title": "Test Frontity Blog",
      "description": "WordPress installation for Frontity development"
  "packages": [
      "name": "test-theme"
      "name": "@frontity/wp-source",
      "state": {
        "source": {
          "url": "",
          "homepage": "/home",
          "postsPage": "/blog"

export default settings;

The root component for testing (/src/components/index.js):

import {connect} from "frontity";

const Root = ({state}) => {
  const data = state.source.get(state.source.postsPage)
  console.log(state.source.postsPage) /*Output: /blog*/
  const items = data.categories
  console.log(items) /*undefined*/

    return (
        You can edit your package in:

  export default connect(Root)

Take into account that issue doesn’t seem to be happening inside the handler as console.log isn’t outputting anything. In theory, this should work, right? Or am I missing something?
