这个错误信息提示了一个Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'list')。根据引用内容中的信息,这个错误一般是由于访问未定义的属性而引起的。在这种情况下,请确保你正在访问一个已经定义的属性。你可以检查一下你的代码,看看在index.vue文件的第162行是否正确地定义了'list'属性。

index.vue:150 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '1')
在你提供的代码中,报错指向了index.vue文件的第150行。错误信息是Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '1')。这个错误的原因是在这一行代码中,尝试读取一个未定义的属性。具体来说,是尝试读取一个数组中的第1个元素,但是该数组是未定义的。
要解决这个错误,可以采取以下几个方法:
方法1:对askData进行判断
可以在渲染页面之前对askData进行判断,判断它是否存在或者是否为空。只有在askData存在时才进行渲染操作,这样就可以避免读取未定义的属性造成的错误。
方法2:在axios请求拦截器中添加配置
在axios请求拦截器中添加配置,确保请求发送前的数据正确。可以通过在请求拦截器中打印config来查看请求的相关配置,确保数据正确传递。
通过以上两种方法的任意一种或者结合使用,你应该可以解决这个错误。记得在代码中进行适当的错误处理和边界条件判断,确保程序的稳定运行。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
