Uncaught (in promise) TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator))

这个错误通常发生在尝试迭代一个未定义的值时。"Uncaught (in promise) TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator))"这个错误给出了一些线索。这意味着你在尝试对一个未定义的值进行迭代操作，而无法使用Symbol(Symbol.iterator)属性。根据提供的信息，可能是在进行懒加载配置时，有一些代码尝试对一个未定义的值进行迭代操作，导致报错。
要解决这个问题，你可以检查你的懒加载配置命令和相应的模块代码。确保你正确地导入和定义了需要迭代的值，并且该值不是未定义的。另外，你也可以检查代码中是否有其他地方尝试对未定义的值进行迭代操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
