Uncaught TypeError: Cannot read properties of null (reading 'children') at <anonymous>:1:59

Uncaught TypeError: Cannot read properties of null (reading 'children')这个错误通常是在代码中尝试读取一个null对象的属性时出现的。在这种情况下，代码尝试在一个值为null的对象上读取名为'children'的属性，但是null对象没有该属性，因此会抛出错误。这种错误通常发生在代码中没有正确地处理变量或对象，导致它们的值为null。要解决这个问题，可以通过检查变量或对象是否为null来避免尝试读取不存在的属性。例如，在访问'children'属性之前，可以使用if语句检查该对象是否为null，如果是，则采取适当的处理措施。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
