Hello Devs, I am getting error at AirFlow UI while running Data Profiling -> Charts.
Query : SELECT state, COUNT(1) as number FROM task_instance WHERE dag_id LIKE 'tutorial%' GROUP BY state Error : SQL execution failed. Details: 'NoneType' object has no attribute 'get_pandas_df' I have installed AirFlow on my Cent OS 7 machine with Python 2.7.5. All workflows are running without any error but charting always fails with above error. Thanks Pari
