我正在尝试创建一个动态块，并遵循文档中描述的步骤，但由于某些原因，返回的内容/wp-json/wp/v2/block-renderer/plugin-blocks/frontpage-releases?context=edit&_locale=user 是Error loading block: No route was found matching the URL and request method 有一个JSON响应{"code":"rest_no_route","message":"No route was found matching the URL and request method","data":{"status":404}} 而不是真正的街区。这是我的代码供您审阅，如果我遗漏了什么，请告诉我。谢谢

实施说明：

所有块都通过React via向下编译laravel-mix 将网页打包到assets/js/blocks.js

在showBlock() 方法是在保存页面时调用的，但不是在编辑器中将其添加到页面内容时调用的，也不是从页面本身调用的当前正在测试分类法或自定义块组是否导致此问题
