The SingleDeviceViewNode gets the outputColumnNames from MergeSortNode in LocalExecutionPlanner. However, in some situation such that only one SingleDeviceViewNode is assigned in data region, the lack of MergeSortNode will cause a null exception in visitSingleDeviceView. !image-2022-12-11-17-16-01-243.png! -- This message was sent by Atlassian Jira (v8.20.10#820010)
