Unable to get get_transactions() to work with GLS and SecureGo

[x1125]

Hey there, I'm trying to switch from ING to GLS and I'm having problems with the TAN procedure.
I think I read all of the documentation and most of the Github issues, but couldn't resolve my issue.

When trying to get the transactions for my GLS account, I get a response like this:

<o.__class__.__name__(command_seg=fints.segments.statement.HKCAZ1(header=fints.formals.SegmentHeader('HKCAZ', 3, 1), account=fints.formals.KTI1(iban='DE31...', bic='GENODEM1GLS'), supported_camt_messages=fints.formals.SupportedMessageTypes(expected_type=['urn:iso:std:iso:20022:tech:xsd:camt.052.001.08']), all_accounts=False), tan_request=fints.segments.auth.HITAN7(header=fints.formals.SegmentHeader('HITAN', 5, 7, 4), tan_process='4', task_reference='...', challenge='Bitte bestätigen Sie den Vorgang in Ihrer SecureGo plus App'))>

When using time.sleep(), accepting the request in the app and doing the same operation again, I'm getting the same result. Sending a tan via python-fints doesn't make any sense.

My code is pretty straight forward:

client = FinTS3PinTanClient(
    identifier,
    user_id,
    pin,
    server,
    product_id=product_id
)

with client:
    assert client.get_current_tan_mechanism() == "946"
    
    account = client.get_sepa_accounts()[0]
    assert str(account.iban).startswith("DE31")
    
    response = client.get_transactions(account)
    if isinstance(response, fints.client.NeedTANResponse):
        print("NeedTANResponse")
        time.sleep(30)

    print(client.get_transactions(account))

The object for the tan mechanism looks like this:

{'946': fints.formals.TwoStepParameters7(security_function='946', tan_process='2', tech_id='DECOUPLED', zka_id='Decoupled', zka_version=None, name='SecureGo plus (Direktfreigabe)', max_length_input=None, allowed_format=None, text_return_value='TAN', max_length_return_value=2048, multiple_tans_allowed=True, tan_time_dialog_association=fints.formals.TANTimeDialogAssociation.NOT_ALLOWED, cancel_allowed=False, sms_charge_account_required=fints.formals.SMSChargeAccountRequired.MUST_NOT, principal_account_required=fints.formals.PrincipalAccountRequired.MUST, challenge_class_required=False, challenge_structured=True, initialization_mode=fints.formals.InitializationMode.CLEARTEXT_PIN_NO_TAN, description_required=fints.formals.DescriptionRequired.MUST_NOT, response_hhd_uc_required=False, supported_media_number=1, decoupled_max_poll_number=150, wait_before_first_poll=2, wait_before_next_poll=2, manual_confirmation_allowed=True, automated_polling_allowed=True)}

Can you help me out there?

Does it work with our sample script?

It works! There's a lot of noise, but I can "Fetch transactions of the last 30 days" just fine, so the error is on my side. Thanks a lot! 👍
