<!-- Greeting --> Hi @maxfrei750! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the superset team. <!-- Answer --> The import error with `{'theme_id': ['Unknown field.']}` in Superset 6.0.0rc1 is caused by a schema mismatch: the import process doesn't recognize the `theme_id` field in dashboard exports. This happens because the export/import logic for dashboards with custom themes was incomplete in that release. A recent fix ([PR #34850](https://github.com/apache/superset/pull/34850))—merged after 6.0.0rc1—completely overhauled theme import/export. Now, dashboards export a `theme_uuid` (not `theme_id`), and the import process maps this UUID to the correct theme ID, auto-bundling themes for portability and providing a graceful fallback if a theme is missing. This resolves the "unknown field" error and makes dashboard import/export with custom themes robust and portable. To resolve your issue, upgrade to a Superset version that includes this fix (any build after September 1, 2025). As a temporary workaround, you could try editing your export files to use `theme_uuid` instead of `theme_id`, but the upgrade is the recommended and supported solution. More details on the fix and new behavior are in [PR #34850](https://github.com/apache/superset/pull/34850). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
