Вопрос Stimulus Hello controller не работает

bundle exec rails webpacker:install:stimulus

<div data-controller="hello">
  <input data-hello-target="name" type="text">

  <button data-action="click->hello#greet">
    Greet
  </button>

  <span data-hello-target="output">
  </span>
</div>

# app/javascript/controllers/hello_controller.js
import { Controller } from "stimulus"

export default class extends Controller {
  static targets = [ "name", "output" ]

  greet() {
    this.outputTarget.textContent =
      `Hello, ${this.nameTarget.value}!`
  }
}

yarn add stimulus-lightbox

// Probably in app/javascript/controllers/index.js
// Load all the controllers within this directory and all subdirectories. 
// Controller files must be named *_controller.js.

import { Application } from "stimulus"
import { definitionsFromContext } from "stimulus/webpack-helpers"
import Lightbox from "stimulus-lightbox"

const application = Application.start()
const context = require.context("controllers", true, /_controller\.js$/)
application.load(definitionsFromContext(context))
application.register("lightbox", Lightbox)

// In your application.js (for example)
import "controllers"
import 'lightgallery/css/lightgallery.css'

  display: grid;
  grid-template-columns: repeat(3, 1fr);
  gap: 40px;
