TypeError: Cannot read property '_vueTypes_name' of null

in Technique[技术] by (71.8m points)

错误是在三级组件传值是出现的。
根组件将data状态使用props属性分别传到父组件和子组件，子组件在执行created钩子函数后初始化赋值时打印了这个错误，而且后续的初始化逻辑因为这个也无法执行了。
代码就不贴了，都是常规的定义使用props方式，使用模板语法或者render函数来传props到子组件，父组件和子组件直接设置或者使用mixins定义props属性。
哪位有经验的大佬能帮忙看下这个问题。

定义props默认值或者判断空值避免报错，添加监听更新就好
