Is there an issue with pyvo.dal.TAPService?

Question

I have been successfully running the code below for several months. Now I get an error: DALServiceError: Cannot wait for job completion. Job is not active!

I have tried repeatedly over the week-end and today and cannot get it to run.

# Get an instance of the TRILEGAL TAP service using PyVO and assert that it exists.

trilegal_tap_url = 'https://datalab.noirlab.edu/tap'

trilegal_tap = pyvo.dal.TAPService(trilegal_tap_url)

assert trilegal_tap is not None

assert trilegal_tap.baseurl == trilegal_tap_url

# Count the stars located in a 9.6°squared area

trilegal_query = """

        SELECT COUNT(*)

        FROM  lsst_sim.simdr2

        WHERE ra > 265.92 AND ra < 269.02 AND dec > -31.86 AND dec < -28.76

        """

job = trilegal_tap.submit_job(trilegal_query)

job.run()

job.wait(phases=['COMPLETED', 'ERROR'])

print('Count stars in selected patch')

print('Job phase is', job.phase)

uttot = job.fetch_result().to_table()

print('count = ',uttot[0][0])
