Getting Error When using Celery Worker

[Asturias-sam]

I have configured the celery worker to run the queries in async mode, but when i am running the queries in sql lab they are getting stuck and getting the below stack trace from logs:

Traceback (most recent call last):
  File "/opt/superset/venv/lib/python3.7/site-packages/superset/result_set.py", line 144, in __init__
    series, type=pa.timestamp("ns", tz=tz)

  File "pyarrow/error.pxi", line 107, in pyarrow.lib.check_status
pyarrow.lib.ArrowTypeError: Did not pass numpy.dtype object
ERROR:superset.result_set:Did not pass numpy.dtype object

Can anyone help me with that ?

@robdiciuccio Rob, maybe you can help?

@Asturias-sam There's a try/except wrapper around this code, so it should only be logging the exception and continuing to process the query. Are you able to run the query directly against the database? Is it a long-running query?

Hello Rob,

When i disable the async mode i able to run the queries but once i enable the query in async i am seeing queries are getting stuck.
No they are not long running queries usually they take 1-2 minute.
