<!-- Answer --> Thanks for clarifying—the column type being "TEXT" is correct. Given that, the most common reasons for 0 rows in the Deck.gl GeoJSON chart are: the dataset schema in Superset not being refreshed after changes, a mismatch in column name or case between your database/view and the chart controls, or a parsing error due to a single malformed or NULL value in the GeoJSON column. Superset's backend is strict—any mismatch or invalid value can cause the chart to show 0 rows, even if SQL Lab displays results. Try syncing (refreshing) your dataset schema in Superset, double-check the selected column name in the chart controls, and test with a minimal dataset (just a few rows, only the GeoJSON column) to rule out data-specific issues. If the problem persists, check the Superset backend logs for errors when loading the chart—any parsing or schema mismatch will usually show up there. More details on the backend flow and strict requirements are [here](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/viz.py). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
