<!-- Answer --> I found some similar discussions and issues that might be relevant to your problem: 1. [Unable to get a screenshot of a chart](https://github.com/apache/superset/discussions/27760) - This discussion is unsolved and was last updated on October 3, 2024 <sup>[[1]](https://github.com/apache/superset/discussions/27760)</sup>. 2. [API /chart/{pk}/cache_screenshot/](https://github.com/apache/superset/discussions/18281) - Another unsolved discussion, last updated on May 8, 2023 <sup>[[2]](https://github.com/apache/superset/discussions/18281)</sup>. 3. [Dashboard Screenshot API Endpoint Gives an Error Message when a Dashboard is Empty or has no Charts](https://github.com/apache/superset/issues/30736) - This issue was closed by a pull request that fixed the problem of downloading a screenshot of an empty dashboard <sup>[[3]](https://github.com/apache/superset/issues/30736)</sup>. Regarding the 404 Not Found error when retrieving the screenshot, here are some potential reasons based on the Superset API behavior: - The `cache_key` might not correspond to a valid cached screenshot. If the screenshot is not found in the cache, a 404 error is returned <sup>[[4]](https://github.com/apache/superset/blob/master/tests/integration_tests/dashboards/api_tests.py)</sup>. - Ensure that the "THUMBNAILS" feature is enabled, as the endpoint will return a 404 error if this feature is not active <sup>[[5]](https://github.com/apache/superset/blob/master/superset/dashboards/api.py)</sup>. - There might be an issue with the caching mechanism in your Docker Compose environment. Proper configuration of the caching layer, often using Redis, is crucial for the efficient caching and retrieval of screenshots <sup>[[6]](https://github.com/apache/superset/blob/master/docs/docs/installation/architecture.mdx)</sup>. You might want to verify these aspects to troubleshoot the issue further. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
