Here's what's happening: The **frontend UI** exclusively edits `warning_markdown` (parsed from `metric.extra.warning_markdown` on load) [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/components/Datasource/DatasourceEditor.jsx#L1576-L1618), but when **saving**, `DatasourceModal` sends `warning_text: metric.warning_text` — which was **never populated** by the UI, so it's empty [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/components/Datasource/DatasourceModal.tsx#L132-L150). The `buildExtraJsonObject` helper does correctly write `warning_markdown` into the `extra` JSON blob [[3]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/components/Datasource/DatasourceModal.tsx#L70-L84), but the **backend PUT schema** (`DatasetMetricsPutSchema`) only accepts `warning_text`, not `warning_markdown` [[4]](https://github.com/apache/superset/b lob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/datasets/schemas.py#L242-L263). So on save, `warning_text` in the database gets overwritten with an empty value, while `extra.warning_markdown` retains the value in the JSON blob. On the next GET, the backend returns both `warning_text` (empty, from the DB column) and `warning_markdown` (populated, from `extra.warning_markdown`) [[5]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/connectors/sqla/models.py#L1099-L1117). The warning icon still shows because it reads from `extra.warning_markdown`, but the text field appears blank depending on which field the UI prioritizes on load. **Suggested fix** — in [`DatasourceModal.tsx`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/components/Datasource/DatasourceModal.tsx#L142-L142), change the metric body construction to copy from the UI-edited field: ```tsx // Before (broken): warning_text: metric.warning_text, // After (fixed): warning_text: metric.warning_markdown, ``` This ensures the value edited in the UI (`warning_markdown`) is persisted to the `warning_text` database column that the backend PUT schema expects. An alternative backend approach would be to also accept `warning_markdown` in `DatasetMetricsPutSchema` and sync it to `warning_text`, but the frontend fix is more straightforward. Note: [PR #39706](https://github.com/apache/superset/pull/39706) fixed a related null-serialization issue in `buildExtraJsonObject` but did not address this underlying field-name mismatch. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](<https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset>).* --- Share context across your team and agents.
