The error message "object of type 'NoneType' has no len()" suggests that there might be an issue with how the API key or another input is being processed or validated. This typically occurs when a function expects a non-null value but receives None instead.

Here are a few steps you can take to troubleshoot and potentially resolve this issue:

1. Check Input Fields: Ensure that all required fields, especially the API key, are filled in correctly. An empty or improperly formatted input might be causing the error.

2. Review the 'Save' Function: The 'Save' function should handle input validation and storage. It should check if the input is empty and display an error message if so. Make sure this logic is correctly implemented and that the input is not being set to None inadvertently ^[1].

3. Debugging: Add logging or print statements in the code where the API key is processed to verify that the input is being correctly captured and is not None.

4. Code Review: Look into the specific part of the codebase that handles the interaction with the Brave Search API, such as the BraveSearchWrapper class in brave_search.py, to ensure that the API key is being used correctly ^[2].

If these steps do not resolve the issue, further investigation into the specific implementation details of the 'Save' function and related code might be necessary.
