Hi @l0uden Thank you for reporting the issue. I was able to reproduce the error. This appears to be a problem with dash-ag-grid and will likely be transferred there for further investigation.

I also noticed this error message:

ag-grid-community.auto.esm.js:438 AG Grid: Grid API function getColumnState() cannot be called as the grid has been destroyed. It is recommended to remove local references to the grid api. Alternatively, check gridApi.isDestroyed() to avoid calling methods against a destroyed grid. To run logic when the grid is about to be destroyed use the gridPreDestroy event. See: See https://www.ag-grid.com/react-data-grid/grid-lifecycle/#grid-pre-destroyed value @ ag-grid-community.auto.esm.js:438
