TypeError: Cannot read properties of undefined (reading '1')报错但是可以获取到值

根据引用的描述，当访问一个对象的属性时，如果该属性不存在，结果会是undefined。但如果接着访问该属性的属性，则会出现TypeError报错。因此，对于报错"TypeError: Cannot read properties of undefined (reading '1')"，虽然报错了但可以获取到值的情况，可能是因为在访问属性时使用了安全访问运算符(?.)。安全访问运算符可以在访问对象属性时，如果属性不存在，则会立即返回undefined，而不会出现TypeError报错。例如，使用store.state.user?.data?.id来访问对象中的属性，如果其中任何一个属性不存在，都会返回undefined而不会报错。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
