What does it mean when the typescript displays an error message "Object may be undefined"?

edit

This error message means that the code is trying to access a property or method on an object that has not been defined or initialized. This can occur when the object is null, undefined, or has not been assigned a value. To fix this error, the code should check if the object exists before trying to access its properties or methods. An example of this would be using the nullish coalescing operator (??) or optional chaining (?) to handle undefined values.
