<!-- Greeting --> Hey there, @maybesheloves! I'm here to help you figure out the issue with Superset 3.0.0. Let's work together to solve this problem. <!-- Answer --> I found a similar unsolved discussion regarding a 'comparator' issue that might be related to network errors in Apache Superset. You can view the discussion [here](https://github.com/apache/superset/discussions/12356) <sup>[[1]](https://github.com/apache/superset/discussions/12356)</sup>. For your specific issue with the network error when adding a chart to a dashboard in Superset 3.0.0, consider checking the following: 1. **Network Request Endpoints**: Superset uses specific endpoints for fetching chart data. Ensure that the `/api/v1/chart/data` endpoint is accessible and not blocked by any network policies <sup>[[2]](https://github.com/apache/superset/blob/master/superset-frontend/src/components/Chart/chartAction.js)</sup>. 2. **Error Messages and Codes**: Superset documents specific error messages and codes related to network errors. Check if the error message corresponds to any documented issues, such as `FRONTEND_NETWORK_ERROR` or `CONNECTION_HOST_DOWN_ERROR` <sup>[[3]](https://github.com/apache/superset/blob/master/superset/errors.py)</sup><sup>[[4]](https://github.com/apache/superset/blob/master/superset-frontend/src/setup/setupErrorMessages.ts)</sup>. 3. **Retry Mechanism**: Superset's frontend has a retry mechanism for network errors, specifically for HTTP status code 503. Ensure that the error you're encountering isn't due to a temporary issue that could be resolved by this retry mechanism <sup>[[5]](https://github.com/apache/superset/blob/master/superset-frontend/packages/superset-ui-core/src/connection/constants.ts)</sup>. 4. **Configuration Settings**: Review your Superset configuration settings, such as `SUPERSET_WEBSERVER_TIMEOUT` and `DASHBOARD_AUTO_REFRESH_MODE`, which could affect network requests for dashboards <sup>[[6]](https://github.com/apache/superset/blob/a49a15f990176c8736ad67d06f74e6eb30b612e4/superset/config.py)</sup><sup>[[7]](https://github.com/apache/superset/blob/89b6d7fb681ed69644c5c5e1a0201209d82518f7/superset/config.py)</sup>. These steps might help you identify and resolve the network error when adding charts to your dashboard. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
