Bug description

We are currently encountering an issue with Apache Superset where we see the following error message intermittently:

"Unable to migrate query editor state to backend. Superset will retry later. Please contact your administrator if this problem persists."

This issue is affecting the user experience as it causes popups in the interface, indicating a failure to persist the query editor state. Despite multiple retries, the state is not being migrated properly, and the error message continues to display. Kindly share the root cause to fix this popup, attached screenshot below for reference,

Hello @thangaSelvanG! I'm Dosu, here to help you tackle bugs, answer questions, and assist you in becoming a contributor. I'm ready to assist while you wait for a human maintainer. Let's get started!

The error message you're encountering, "Unable to migrate query editor state to backend," can be caused by several factors:

  1. Network or Backend Issues: The migration relies on HTTP POST requests to the Superset backend. Network issues or backend service unavailability can lead to migration failures [1].

  2. Feature Flag Configuration: If the SQLLAB_BACKEND_PERSISTENCE feature flag is off, the state remains in local storage, which can cause issues if the flag is toggled without proper migration [2].

  3. State Conflicts: Conflicts between local storage and backend state, such as unsaved updates or discrepancies in query editor IDs, can cause migration issues [1].

  4. Local Storage Handling: Errors in reading or parsing local storage data can lead to migration failures. The code attempts to migrate state from local storage to the backend when the feature flag is enabled [1].

To address this issue, ensure that your network connection is stable and that the backend services are running correctly. Verify that the SQLLAB_BACKEND_PERSISTENCE feature flag is configured as intended. Additionally, check for any conflicts or unsaved updates in the query editor state that might be causing the migration to fail.

@thangaSelvan Could you pls send the sceenshot of the db connections which you added (Settings -> Database Connections). This error shows when there is no db connection added. It will help me to troubleshoot the issue as I can already see a db added in your screenshot. Thanks :)

@pedram-tehranchi I suppose @MonseiurY 's question goes for you too, then... any help to make this reproducible would be appreciated.
