<!-- Answer --> Ensure that the `THUMBNAIL_EXECUTORS` configuration is correctly set in your `superset_config_docker.py`. It should be defined as follows: ```python from superset.tasks.types import ExecutorType THUMBNAIL_EXECUTORS = [ExecutorType.CURRENT_USER] ``` If you have already set this and the issue persists, consider the following: 1. **Check Redis Connection**: Verify that your Redis server is running and accessible. Use a Redis client to connect to the server and ensure it is reachable at the specified host and port. 2. **Review Logs**: Check the Superset and Celery worker logs for any error messages or stack traces that might provide more insight into the issue. 3. **Playwright and Browser Dependencies**: Ensure that Playwright and the necessary browser dependencies are installed and up-to-date. Run `playwright install` to ensure all required components are installed. 4. **Celery Worker Configuration**: Make sure your Celery workers are running and properly configured to handle thumbnail generation tasks. Check that they have access to the necessary environment variables and configurations. If these steps do not resolve the issue, further investigation into the logs and configurations may be necessary to identify any underlying problems. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
