Here are some common causes of this error:
- A variable that is supposed to contain an object is not defined or is null.
- A function is being called on an object that is not an instance of the correct class or constructor.
- A property or method is being accessed on an object that does not have that property or method.
To fix this error, you will need to identify the specific object that is causing the problem and ensure that it is properly defined and initialized. This may involve checking the variable or object that is being referenced, the function that is being called, or the property or method that is being accessed.
It’s also a good practice to use try-catch block to handle any exception and get the error message with more details, which will help you to debug the issue.
