AttributeError: 'NoneType' object has no attribute 'services'

I'm trying to pull down the hCG beta subunit protein via UniProt accession number and keep running into an AttributeError. I've tried the command python ProteinCartography/fetch_accession.py -a P0DN86 -o input -f fasta pdb and receive the following error:

Traceback (most recent call last):
  File "/Users/jasmine/ArcadiaScience/ProteinCartography/ProteinCartography/fetch_accession.py", line 94, in <module>

    fetch_fasta(accession, output_dir)

    u.services.settings.MAX_RETRIES = DefaultExpBackoffRetry()
AttributeError: 'NoneType' object has no attribute 'services'

I looked at line 59 of the api_utils.py file and u.services.settings.MAX_RETRIES = DefaultExpBackoffRetry() seems to be the issue. Is this a problem with bioservices or am I doing something completely wrong? I also checked to make sure that bioservices is included in the cartography_tindy conda environment.

(note for PC dev team):

change:

class UniProtWithExpBackoff(UniProt):
    """
    Specialize the UniProt class to set the MAX_RETRIES to be a DefaultExpBackoffRetry
    object.
    """

    def __init__(self, *args, **kwargs):
        u = super().__init__(*args, **kwargs)
        u.services.settings.MAX_RETRIES = DefaultExpBackoffRetry()

to:

class UniProtWithExpBackoff(UniProt):
    """
    Specialize the UniProt class to set the MAX_RETRIES to be a DefaultExpBackoffRetry
    object.
    """

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.services.settings.MAX_RETRIES = DefaultExpBackoffRetry()

This should be resolved as of the most recent release.
