In version 4.1.1, the `/thumbnail/<digest>/` endpoint was updated to handle cache misses by initiating an asynchronous task to compute the thumbnail if it does not exist in the cache <sup>[[1]](https://github.com/apache/superset/blob/master/superset/dashboards/api.py)</sup>. Here are a few things you can check or try: 1. **Feature Flags and Configuration**: Ensure that the `FeatureFlag.Thumbnails` is enabled in your configuration. This flag controls the visibility of thumbnails in the frontend <sup>[[2]](https://github.com/apache/superset/blob/master/superset/config.py)</sup>. 2. **Cache Configuration**: Verify that your cache system is properly configured and operational. Thumbnails are stored in the cache, and any issues with the cache could affect their display. 3. **Celery Workers**: Make sure that your Celery workers are running correctly, as they are responsible for processing the asynchronous tasks that generate thumbnails. 4. **Browser Cache**: Clear your browser cache or try accessing the dashboard in an incognito window to rule out any caching issues on the client side. 5. **Logs and Errors**: Check the Superset logs for any errors related to thumbnail generation or caching. This might provide more insight into what is going wrong. If these steps do not resolve the issue, it might be helpful to look into any specific changes made to the `DashboardCard` component or related components between versions 4.0.2 and 4.1.1, as these could also impact thumbnail rendering. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
