Full stack from logs: 2018-02-12 12:29:31,553:ERROR:root:could not broadcast input array from shape (26896) into shape (1,164) Traceback (most recent call last): File "/home/superset/superset-vevn/lib/python3.5/site-packages/superset/views/core.py", line 2188, in sql_json query_id=query_id, return_results=True) File "/home/superset/superset-vevn/lib/python3.5/site-packages/celery/local.py", line 191, in __call__ return self._get_current_object()(*a, **kw) File "/home/superset/superset-vevn/lib/python3.5/site-packages/celery/app/task.py", line 380, in __call__ return self.run(*args, **kwargs) File "/home/superset/superset-vevn/lib/python3.5/site-packages/superset/sql_lab.py", line 94, in get_sql_results ctask, query_id, return_results, store_results, user_name) File "/home/superset/superset-vevn/lib/python3.5/site-packages/superset/sql_lab.py", line 245, in execute_sql 'data': cdf.data if cdf.data else [], File "/home/superset/superset-vevn/lib/python3.5/site-packages/superset/dataframe.py", line 55, in data for row in self.__df.values] File "/home/superset/superset-vevn/lib/python3.5/site-packages/pandas/core/generic.py", line 3272, in values return self.as_matrix() File "/home/superset/superset-vevn/lib/python3.5/site-packages/pandas/core/generic.py", line 3253, in as_matrix return self._data.as_matrix(columns).T File "/home/superset/superset-vevn/lib/python3.5/site-packages/pandas/core/internals.py", line 3450, in as_matrix return mgr._interleave() File "/home/superset/superset-vevn/lib/python3.5/site-packages/pandas/core/internals.py", line 3477, in _interleave result[rl.indexer] = blk.get_values(dtype) ValueError: could not broadcast input array from shape (26896) into shape (1,164) ### Steps to reproduce Run query: SELECT a.id, max(b.created) FROM a LEFT JOIN b ON b.owner_id = a.id GROUP BY a.id Without a.id in the result, the query executes giving the odd results. It returns much more results than it should. Execution in psql works fine as well.
