get_vulnerabilities call can give a stacktrace: HTTPException('got more than 100 headers')

Trying to retrieve vulnerability information for CVE-2020-27216 (and potentially others I suppose) produces a stacktrace (or 3). The following code snippet highlights the issue (noting that line 3 runs fine, but fails on line 4):

from blackduck.HubRestApi import HubInstance
hub = HubInstance()
hub.get_vulnerabilities('CVE-2021-26117')
hub.get_vulnerabilities('CVE-2020-27216')

and the stacktrace produced is below:

Traceback (most recent call last):
  File "C:\Users\me\.virtualenvs\blackduck\lib\site-packages\urllib3\connectionpool.py", line 699, in urlopen
    httplib_response = self._make_request(

    raise HTTPException("got more than %d headers" % _MAXHEADERS)

During handling of the above exception, another exception occurred:
