This is an excellent and thorough bug report — the analysis is spot-on. I can confirm both issues are still present in the current codebase: - `deck_multi` still has `useLegacyApi: true` set in its plugin metadata [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/legacy-preset-chart-deckgl/src/Multi/index.ts#L32), and `Multi.tsx` still fetches sub-layers via `getExploreLongUrl` → `SupersetClient.get` against the legacy `explore_json` endpoint [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/plugins/legacy-preset-chart-deckgl/src/Multi/Multi.tsx#L140-L145). - The `DeckPathViz.get_properties` deserialization code that assumes `line_column` is a string is still present in `viz.py` [[3]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/viz.py#L1894-L1895), with no guard around the per-slice `get_payload()` call in `DeckGLMultiLayer.get_data()`. - The `explore_json` endpoint remains active (deprecated, marked for removal in 5.0.0) and still short-circuits into the async path when `GLOBAL_ASYNC_QUERIES` is enabled [[4]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/views/core.py#L260-L263). Regarding the broader migration: [PR #41714](https://github.com/apache/superset/pull/41714), which coordinates the full legacy removal (including `viz.py` and `explore_json`), is still open [[5]](https://github.com/apache/superset/pull/41714). [PR #41730](https://github.com/apache/superset/pull/41730), which was supposed to migrate `deck_multi` specifically, was merged on July 3 [[6]](https://github.com/apache/superset/pull/41730), but the legacy code paths are clearly still in place — possibly indicating the migration is incomplete or in an intermediate state pending #41714's merge. [Issue #41047](https://github.com/apache/superset/issues/41047) ("Make the Deck.GL plugin non-legacy") also remains open [[7]](https://github.com/apache/superset/issues/41047#issuecomment-4909773893). Your suggested fix #2 (marking sub-layer requests so `explore_json` answers them synchronously) seems like the most pragmatic short-term approach for Cause 1, since it's low-risk and, as you noted, the parent request has already done the query work. For Cause 2, normalizing the `line_column` value to match the client-side transform and wrapping per-slice `get_payload()` to isolate failures both seem clearly correct. A PR covering these would be welcome while the full legacy migration is still in progress. <!-- 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>).* --- Docs are dead.
