Create Dashboard API not working about superset HOT 1 OPEN

The error you're encountering with the GuestUser object and the Dashboard API in Superset seems to stem from an issue where the GuestUser is expected to behave like a SQLAlchemy model instance but doesn't meet these expectations. This is likely due to the GuestUser object, which is designed for guest authentication, not being properly integrated with SQLAlchemy for operations that require database interaction.

To address this issue, consider the following steps:

1. Review the Authentication Flow: Ensure the process that handles guest tokens and creates GuestUser objects is correctly implemented, especially in how these objects are used in database operations.

2. Adjust Middleware or Decorators: If there's middleware or decorators involved in user handling based on tokens, make sure they correctly manage guest tokens to avoid database operations expecting a fully-fledged user model.

3. Custom Handling for GuestUser: Implement custom handling in parts of your application where GuestUser objects might lead to issues, ensuring operations that expect database model attributes like _sa_instance_state are properly managed.

4. Check for Similar Issues: A similar issue was noted and resolved in a past version of Superset. Although you're using version 4.0.1, and the issue was noted to be resolved by upgrading to version 3.0.1, it's worth checking the Superset GitHub issues for any related discussions or fixes that might be applicable to your version.

This approach focuses on ensuring that GuestUser objects are handled appropriately within the context of your application's authentication flow and database interactions. If the issue persists, reviewing the implementation of GuestUser and its interaction with SQLAlchemy might provide further insights.
