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

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'then') 错误是由于在调用.then()方法之前，出现了一个undefined的对象，导致无法读取属性。这个错误通常发生在Promise链式调用中。根据提供的引用内容，我们可以看到这个错误可能是在queGetdata函数中出现的。和中都提到了这个错误的解决方法，即将resolve()放在commit()方法之前。这是因为在Promise的then()方法中，如果在commit()之前调用resolve()，则会在后续的处理中出现undefined的错误。通过将resolve()放在commit()之前，可以确保在commit()被调用之前，Promise已经成功地执行了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
