Cannot read properties of undefined (reading 'categoryList')

这个错误是因为在代码中试图读取一个未定义的属性categoryList'。根据引用和引用，可以看出这个错误是因为在某个地方使用了'categoryList'但它没有被正确初始化。这可能是因为在初始化之前就尝试访问了该属性，或者在初始化过程中出现了问题。为了解决这个问题，你可以检查代码确保在使用'categoryList'之前它已经被正确初始化。你也可以查看代码中的初始化过程，确保没有出现任何错误导致初始化失败。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
