oP = OpenProject(url=os.getenv('OP_URL'), api_key=os.getenv('OP_APIKEY'))
wS = oP.get_work_package_service()
aT = oP.get_attachment_service()

updates_wP = wS.find_all()
wP_undict = json.dumps(updates_wP[0].__dict__)
wp_dict = json.loads(wP_undict, object_hook=lambda d: SimpleNamespace(**d))

attachment = json.loads(json.dumps(aT.create(filename="openproject.png",description="Openproject logo!",file_path='openproject.png').__dict__), object_hook=lambda d: SimpleNamespace(**d))

a = Attachment({'id': int(attachment.id)})
find = aT.find(a)
