Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'data'

根据引用和引用的内容，出现了错误"Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'data')"的原因是在调用resolve之前，尝试读取了一个未定义的属性 'data'。这是因为在commit之前的代码中，应该先调用resolve(data)，然后再调用context.commit方法，这样才能确保在commit方法中能够正确获取到data的值。

另外，根据引用的内容，如果在.catch((e) => {})中捕获错误并处理，那么就不会报错了。所以，可以将.catch((e) => {})添加到promise链的最后，以处理错误并防止报错。

综上所述，修复该错误的方法是在调用resolve(data)之后再调用context.commit方法，并将.catch((e) => {})放在promise链的最后来处理错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
