MaxRetryError with Docusign in Django

Question

I am working on a webapp for my company. After the user enters information into the form that I provide, a pdf form is generated (using weasyprint), filling in the customer's information into the fields necessary. However, I am needing to integrate docusign's webapi into my project. I have messed around with the code a bit, and have gotten to the current point below:

def Signview(request):

    username = "myDocusignUsername"
    integrator_key = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
    base_url = "https://demo.docusign.net/restapi"
    oauth_base_url = "account-d.docusign.com/oauth/auth?request_type=code&scope=signature&client_id=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx&redirect_uri=http://localhost:8000/page/to/redirect/to"
    redirect_uri = "http://localhost:8000/page/to/redirect/to"
    private_key_filename = "createquote/keys/pKey.txt"
    user_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

    file_contents = open("path/to/mydoc.pdf", 'rb').read()

    envelope_definition = docusign.EnvelopeDefinition()
    envelope_definition.email_subject = 'My email subject'
    envelope_definition.email_blurb = 'My email blurb'

    doc = docusign.Document()
    base64_doc = base64.b64encode(file_contents).decode('utf-8')
    doc.document_base64 = base64_doc
    doc.name = "mydoc.pdf"
    doc.document_id = '1'
    envelope_definition.documents = [doc]

    signer = docusign.Signer()
    signer.email = loa.email
    signer.name = loa.ainame
    signer.recipient_id = '1'

    sign_here = docusign.SignHere()
    sign_here.document_id = '1'
    sign_here.page_number = '1'
    sign_here.recipient_id = '1'
    sign_here.x_position = '100'
    sign_here.y_position = '100'
    sign_here.scale_value = '0.5'

    tabs = docusign.Tabs()
    tabs.sign_here_tabs = [sign_here]
    signer.tabs = tabs

    recipients = docusign.Recipients()
    recipients.signers = [signer]
    envelope_definition.recipients = recipients

    envelope_definition.status = 'sent'

    auth_api = AuthenticationApi()
    envelopes_api = EnvelopesApi()

    try:
        login_info = auth_api.login(api_password='true', include_account_id_guid='true')
        assert login_info is not None
        assert len(login_info.login_accounts) > 0
        login_accounts = login_info.login_accounts
        assert login_accounts[0].account_id is not None

        base_url, _ = login_accounts[0].base_url.split('/v2')
        self.api_client.host = base_url
        docusign.configuration.api_client = self.api_client

        envelope_summary = envelopes_api.create_envelope(login_accounts[0].account_id, envelope_definition=envelope_definition)
        assert envelope_summary is not None
        assert envelope_summary.envelope_id is not None
        assert envelope_summary.status == 'sent'

        print("EnvelopeSummary: ", end="")
        pprint(envelope_summary)

    except ApiException as e:
        print("\nException when calling DocuSign API: %s" % e)
        assert e is None # make the test case fail in case of an API exception

    return HttpResponse({'sent'})

This being based on the code located here: https://github.com/docusign/docusign-python-client/blob/master/test/unit_tests.py , Lines 129 through 194.

What I am trying to do is have the document that was generated (and saved to the models in the database I have) sent in an email (automatically) containing the form to be signed using Docusign's Python SDK. However, when I run this code and reach this particular view, I get the following error:

Does anyone know what I am doing wrong here? I really am lost, and Docusign doesn't provide guidance for the WebAPI, from what I've been told when I called them.

Thank you in advance!

This was recently opened and resolved for the python API (https://github.com/docusign/docusign-python-client/issues/15), but the change has not been released yet.

Either way, since you want to use the demo URL, you will need to override it like you are doing above. The specific problem you are having is that the AuthenticationApi using the wrong url. You need to pass it the api client:

auth_api = AuthenticationApi(api_client=api_client)
