我已经使用 CMP 提供商的代码设置了一个自定义模板，该模板非常适合同意设置。我们必须对所提供的 CMP 进行一些添加和编辑。我想在同意更新时发送自定义事件以用作某些标签的触发器，但我不断收到“'dataLayer'未定义”错误。看来我根本无法让沙盒 JavaScript 与我的 dataLayer 对话，因为对它或窗口的任何引用都会产生问题。
我认为这是自定义模板限制的问题。我想了解为什么它不起作用以及如何能够将自定义事件发送到沙盒 JavaScript 中的数据层。
我尝试了不同的方法来尝试完成这项工作，但我尝试的所有方法都会导致“窗口未定义”或“数据层”未定义错误。我的提供商不愿意提供帮助，因为他们认为这是 Google 问题。注意：如果我删除对窗口和数据层的引用，并且按应有的方式更新同意，则脚本可以正常工作。但是，我也需要发送自定义事件作为“updateConsentState”的一部分来触发其他标签。
请参阅下面我的代码：
// Initialize dataLayer
window.dataLayer = window.dataLayer || [];
// Enter your template code here.
const log = require('logToConsole');
const setDefaultConsentState = require('setDefaultConsentState');
const updateConsentState = require('updateConsentState');
const injectScript = require('injectScript');
const queryPermission = require('queryPermission');
const copyFromWindow = require('copyFromWindow');
log('data =', data);
// set default consent
setDefaultConsentState({
'ad_storage': 'denied',
'analytics_storage': 'denied',
'ad_user_data': 'denied',
'ad_personalization':'denied',
'functionality_storage': data.functional,
'personalization_storage': data.functional,
'security_storage': 'granted'
});

要推送到数据层，您可以使用 createQueue API（如果您使用现有窗口变量的名称，它将重用该变量而不是覆盖它）。
这是文档中提到的：
const dataLayerPush = createQueue('dataLayer');
dataLayerPush({'currency': 'USD'}, {'event': 'myConversion'});
如果您想使用它，您需要检查您的 access_global 权限并确保您已允许访问 dataLayer 全局变量（或您的变量的名称）。
