Your question is very vague and missing detail information. But you might just be missing an = when checking undefined. Otherwise, add more info and the actual code where the error occurs.

通用答案是如果您尝试使用一个为null的对象，则可能发生此错误."

通常，在使用对象时，一种更好的做法是检查对象的可为空性，以免出现此类意外情况.
同样，围绕任何关键功能的try-catch块也将停止在浏览器上显示的难看错误.有关更多详细信息，请检查 www.w3schools.com/js/js_errors.asp [

Generic answer would be "this error can occur if you are trying to use an object which is null."

In general, when you are using an object, its a better practice to check object for nullability to avoid such surprises.
Also a try-catch block surrounding any critical functionality would also stop ugly errors showing up on browser. For more details check www.w3schools.com/js/js_errors.asp[^]

Please provide code snippet where this error is occuring then we might be able to give you pin-point answer.
