Invalid Value Error

[IndexEng]

I have copied the get_transactions_by_account example and have included the correct api key and account/budget id. Returning an error:

raise ValueError("Invalid value for `flag_color`, must not be `None`")  # noqa: E501
ValueError: Invalid value for `flag_color`, must not be `None`

Not sure if there is a data problem with my account?

Getting the same error here too.
{'account_id': '604db576-*********-c2c5defe2d64', 'account_name': 'Kredittkort', 'amount': 98240, 'approved': True, 'category_id': None, 'category_name': None, 'cleared': 'reconciled', 'date': '2018-12-21', 'deleted': False, 'flag_color': None, 'id': 'e72efb67-****-4de1-****-4debd70e815a', 'import_id': 'YNAB:98240:2018-12-21:1', 'memo': 'Månedlig Betaling Kredittkort', 'payee_id': 'c1811603-****-40a7-b7a6-272afd898162', 'payee_name': 'Transfer : Utgiftskonto', 'subtransactions': [], 'transfer_account_id': '80da75df-****-4ded-9485-beabcc3e6401', 'transfer_transaction_id': 'a8652e3a-****-40fc-8f9f-8a5e1ee61fe1'}

This response object indicates that flag_color is a valid response. Should the API be updated likewise?
Removing the None checks from transaction_detail.py enables transactions to be listed according to the example file, but are not this file auto-generated by Swagger?

Was not able to resolve this issue myself. Found it easier just using the request library and access the YNAB API directly. Doesn't have a lot of the features of this repository but got the job done.
