这个错误通常发生在尝试访问空值(null)或未定义(undefined)对象的属性时。根据你提供的错误消息,看起来你尝试访问一个名为 'isCE' 的属性,但对象是空值。
要解决这个问题,你可以检查代码中涉及到该属性的部分,并确保在访问之前对象已被正确地初始化。
例如,你可以使用条件语句来检查对象是否为空值或未定义,然后再访问属性:
```javascript
if (obj && obj.isCE) {
// 执行操作
}
```
这样可以防止在对象为空值时引发错误。请注意,根据你的具体情况,可能需要根据实际需求进行相应的修改。

Uncaught TypeError: Cannot read properties of null (reading 'isCE')
This error occurs when you are trying to access a property or method of an object that is null or undefined.
For example, if you have the following code:
```
let myObject = null;
console.log(myObject.isCE);
```
You will get the "Uncaught TypeError: Cannot read properties of null (reading 'isCE')" error because myObject is null and does not have an isCE property.
To fix this error, you should check if the object is null or undefined before accessing its properties or methods.
Here's an example of how you can fix the above code:
```
let myObject = null;
if (myObject !== null && myObject !== undefined) {
console.log(myObject.isCE);
}
```
This code checks if myObject is not null and not undefined before trying to access its isCE property.
