Fix TypeError

✅ Solution

The TypeError usually arises when accessing attributes or methods on a NoneType object where an object of a different type was expected. To fix this, add a check to ensure that the object (e.g., `completion.candidates[0].content.parts`) is not None before attempting to access its members; if it is None, handle the case gracefully, like returning a default value or skipping the problematic section. This prevents the code from attempting operations on a null value, resolving the TypeError.
