Cannot read properties of null (reading '_katavorioDrag')"

Cannot read properties of null (reading '_katavorioDrag')报错是由于在代码中尝试读取一个空对象的属性所导致的。具体来说，无法从null对象（或者指向null的引用）中读取'_katavorioDrag'属性。该错误通常发生在尝试访问一个不存在或未初始化的对象属性时。你可以检查代码中相关的对象是否被正确初始化或者是否存在。还可以使用条件语句或者选项卡来处理可能为空的情况，以避免出现该错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
