403 forbidden errors running test suite during conda build

When running the test suite as part of the gracedb-sdk conda build, I get the same 403 (forbidden) error three times:

requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://gracedb-test.ligo.org/api/superevents/TS110914avv/signoffs/
