<!-- Answer --> To resolve the "ExecutorNotFoundError: Scheduled task executor not found" error, ensure that the `THUMBNAIL_EXECUTORS` configuration in your `superset_config.py` is correctly set up. This error typically occurs due to a misconfiguration of the executors used for thumbnail caching tasks. 1. **Verify `THUMBNAIL_EXECUTORS` Configuration**: Check that the `THUMBNAIL_EXECUTORS` setting is correctly defined in your configuration file. The default configuration is `[ExecutorType.CURRENT_USER]` <sup>[[1]](https://github.com/apache/superset/blob/master/superset/config.py)</sup>. 2. **Check Executor Availability**: Ensure that the executors you have defined are available and correctly implemented. The `get_executor` function should be able to fetch the executor based on your configuration. If the configuration is correct and the error persists, review the implementation of the `get_executor` function to ensure it aligns with your setup <sup>[[2]](https://github.com/apache/superset/blob/master/superset/tasks/cache.py)</sup><sup>[[3]](https://github.com/apache/superset/blob/master/superset/tasks/thumbnails.py)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
