<!-- Answer --> The error you're encountering indicates that the `load_user` function in the Flask App Builder security manager is returning `None`, and the code is attempting to access the `is_active` attribute on this `None` object. This typically happens when the user ID cannot be found or the user is not properly loaded. Here are a few steps you can take to troubleshoot and potentially fix this issue: 1. **Check User ID Retrieval**: Ensure that the user ID is being correctly retrieved and passed to the `load_user` function. If the user ID is `None` or invalid, the function will return `None`. 2. **Verify User Existence**: Make sure that the user exists in your database and is active. If the user does not exist or is inactive, the `load_user` function might return `None`. 3. **Custom `superset_config.py`**: Review your custom `superset_config.py` file to ensure that any custom authentication logic or user loading mechanisms are correctly implemented. Any misconfiguration here could lead to the user not being loaded properly. 4. **Debugging**: Add logging or debugging statements in your custom configuration or user loading logic to trace the flow and identify where it might be failing. 5. **Session Management**: Ensure that session management settings in `superset_config.py` are correctly configured, as they can affect user authentication and session persistence. By following these steps, you should be able to identify the root cause of the issue and resolve it. If the problem persists, further investigation into the specific customizations in your `superset_config.py` might be necessary. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
