Research direction
Investigate the CellWriteHandler lifecycle to determine when the sheet row is accessible. The current approach of cell.getRowIndex() returns null because the row may not have been created yet. Look into the RowWriteHandler or data model to access the underlying data list. Check if there are existing solutions or workarounds in the repository's issues or documentation.
