我正在尝试使用我的Rails 7应用程序来设置Cable，该应用程序使用了importmaps。一切都在开发中工作，但在生产中我的通道JavaScript找不到：
Failed to load resource: the server responded with a status of 404 ()为我的所有notifications_channel.js和所有其他渠道。
有什么我遗漏的吗？我没办法了。
我的设置如下：

ruby "3.0.0"
gem "rails", "~> 7.0.4", ">= 7.0.4.3"

javascript/application.js

console.log("application.js")
import "@hotwired/turbo-rails"
import "controllers"
import "channels"

// Start StimulusJS
import { Application } from "@hotwired/stimulus"

const application = Application.start();

javascript/channels/index.js
import "./notification_channel"
javascript/channels/notification_channel.js

consumer.subscriptions.create("NotificationChannel", {
  connected() {
    console.log("connected NotificationChannel")
    // Called when the subscription is ready for use on the server
  },

  disconnected() {
    console.log("disconnected NotificationChannel")
    // Called when the subscription has been terminated by the server
  },

  received(data) {
    console.log(data)
    let element = document.getElementById("flashes")
    element.insertAdjacentHTML('beforeend', data.html);
  }
});

channels/notification_channel.rb

class NotificationChannel < ApplicationCable::Channel
  def subscribed
    stream_from "notification_channel"
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end
end

production.rb

config.action_cable.allowed_request_origins = [ "https://myapp.hatchboxapp.com", /http:\/\/localhost*/]

  config.hosts << "myapp.hatchboxapp.com"
  config.hosts << "localhost"

这是我的importmap.rb

# Pin npm packages by running ./bin/importmap pin tailwindcss-stimulus-components

pin "application", preload: true
pin "@hotwired/turbo-rails", to: "turbo.min.js", preload: true
pin "@hotwired/stimulus", to: "https://ga.jspm.io/npm:@hotwired/[email protected]/dist/stimulus.js"
pin "@hotwired/stimulus-loading", to: "stimulus-loading.js", preload: true
pin_all_from "app/javascript/controllers", under: "controllers"
pin "@rails/request.js", to: "https://ga.jspm.io/npm:@rails/[email protected]/src/index.js"
pin "tailwindcss-stimulus-components", to: "https://ga.jspm.io/npm:[email protected]/dist/tailwindcss-stimulus-components.module.js"

pin "@rails/actioncable", to: "actioncable.esm.js"
pin_all_from "app/javascript/channels", under: "channels"

cable.yml

development:
  adapter: redis
  url: redis://localhost:6379/1

test:
  adapter: test

production:
  adapter: redis
  url: <%= ENV.fetch("REDIS_URL") { "redis://localhost:6379/1" } %>
  channel_prefix: linus_production

ENV.fetch("REDIS_URL")返回一个有效的url：
