根据提供的引用内容,当出现"TypeError: Cannot read properties of undefined"错误时,通常是因为尝试读取一个未定义的属性。在引用中,报错的具体内容是"Cannot read properties of undefined (reading 'comcode')"。在引用和引用中,报错的具体内容分别是"Cannot read properties of undefined (reading 'id')"和"Cannot read properties of undefined (reading 'tsaRatio')"。
这个错误通常发生在尝试访问一个对象的属性时,而该对象是未定义或为空。在引用中提到,当尝试访问`store.user.state.userInfo.data`时,`userInfo`是一个空对象,`data`属性是未定义的。同时,当尝试继续访问`store.user.state.userInfo.data.id`时,会报错"Cannot read properties of undefined (reading 'id')",因为在这种情况下,属性`data`是未定义的,无法继续访问其子属性`id`。
所以,当出现"TypeError: Cannot read properties of undefined"错误时,需要检查代码中访问的对象是否已经定义和赋值。可能需要在访问对象属性之前添加判断条件,以确保对象存在并且属性已经定义。
