Start by inspecting TableRecords.buildRecords at line 185, then trace how BaseTransactionalExecutor.buildTableRecords and UpdateExecutor.beforeImage reach it. Use the provided ExecuteTemplate stack trace to investigate the null value and reproduce the failing transactional update. Done means the reported null-pointer failure is resolved and the client no longer receives this exception.
