Assuming you are asking about the [object Object] error, this is usually caused by trying to access a property or method on an object that does not exist. For instance, if you have an object with a property called "name" and you try to access the "age" property, you will get this error. This can be fixed by either making sure the property you are trying to access exists, or by using type-checking to make sure the object is the correct type before trying to access the property.
