Hi, I am experience the following behavior:

def getDeviceDetail(client=None, auth=None, dbid=None): from lxml import etree component = dict({'type':'device', 'dbid':dbid}) print(component) node = client.create_message(client.service, 'detailQuery', auth=auth, component=component) print(etree.tostring(node, encoding="unicode", pretty_print=True)) r = client.service.detailQuery(auth=auth, component=component)

getDeviceDetail(client=client, auth=creds, dbid=1234)

The output is as follows:

print(component): {'type': 'device', 'dbid': 1234}
print(etree.tostring(node, encoding="unicode", pretty_print=True)):
(Skipping the rest of the output) <component type="NotSet" dbid="NotSet"/>

zeep version is 3.4.0
Any idea?
