rusackas opened a new pull request, #41840:
URL: https://github.com/apache/superset/pull/41840

   ### SUMMARY
   
   Test-only PR that proves #35087 is fixed on master, and closes it.
   
   The issue reported `Unexpected error: TypeError: Do not know how to 
serialize a BigInt` when clicking "Add or edit filters" on a dashboard where a 
chart had queried a BigInt column. The crash came from `JSON.stringify(charts)` 
in a `useMemo` dependency array in `FiltersConfigForm`, evaluated on every 
render of the filters config modal — chart data responses containing integers 
beyond `Number.MAX_SAFE_INTEGER` are parsed into native `BigInt` values by 
`parseResponse` (`parseMethod: 'json-bigint'`), and `JSON.stringify` throws on 
any `BigInt`.
   
   That stringify call was fixed by #34539 (merged Aug 2025), which serializes 
only the chart ids. However, #34539's regression test only covered opening the 
modal onto an existing filter configuration (`createNewOnOpen: false`), while 
the issue's repro is the fresh "Add or edit filters" flow that auto-creates a 
new filter. This PR adds a test for that exact path and strengthens the shared 
fixture with a value above `Number.MAX_SAFE_INTEGER` (`9007199254740993n`), 
mirroring what `parseResponse` actually produces for large integer columns.
   
   The new test passes on master, confirming the reported path no longer 
throws. No production code changes.
   
   closes #35087
   
   ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF
   
   N/A (test-only change)
   
   ### TESTING INSTRUCTIONS
   
   ```bash
   cd superset-frontend
   npm run test -- 
src/dashboard/components/nativeFilters/FiltersConfigModal/FiltersConfigModal.test.tsx
 --maxWorkers=2
   ```
   
   The new test is `creates a new filter when a chart contains BigInt values`. 
To see it fail as it would have before the fix, revert the #34539 change in 
`FiltersConfigForm.tsx` (restore `JSON.stringify(charts)` in the 
`initiallyExcludedCharts` dependency array) and re-run — the render throws 
`TypeError: Do not know how to serialize a BigInt`.
