AttributeError: 'tuple' object has no attribute 'goal'

This error message is indicating that you are trying to access an attribute called "goal" on a tuple object, but tuples do not have a "goal" attribute.

It is possible that you are trying to access a property of an object that is actually a tuple instead of the expected object type. You may need to double-check your code and make sure that you are accessing the correct object and attribute.

If you are trying to use a tuple to store data that includes a "goal" attribute, you may need to consider using a different data structure, such as a dictionary or a custom object, that can store the necessary data and attributes.
