I have WSDL envelope like this:

...
<xs:complexType name="hilfsmittelattribute">
    <xs:sequence>
        <xs:any maxOccurs="unbounded" namespace="http://hma.ws.bswsnt.vsa/xsd" processContents="skip"/>
    </xs:sequence>
</xs:complexType>
...

What I would like to do is something like this

conn = zeep.Client(...)
data = {
    ....
    'hilfsmittelattribute': {'koerperhaelfte': 1}
    ...
}
pack = conn.service.someMethod(**data)

but I get error that

TypeError: ... got an unexpected keyword argument 'koerperhaelfte'. Signature: `_value_1: ANY[]`

I read documentation from here Zeep documentation for Any

But:

if I do:

conn.get_element('ns0:hilfsmittelattribute') # or ns1, ns2, ns3...

I get

LookupError: No element 'hilfsmittelattribute' in namespace http://ws.bswsnt.vsa/xsd. Available elements are:  -

But if I write

hilfsmittelattribute_type = conn.get_type('ns2:hilfsmittelattribute')

I get the type object

( the code return )

hilfsmittelattribute_type.elements
>> [('_value_1', <Any(name=None)>)]

but if I would like to use this type object like this

hilfsmittelattribute_ = xsd.AnyObject(
    hilfsmittelattribute_type, hilfsmittelattribute_type(koerperhaelfte='1'))

I get the error

TypeError: {...}hilfsmittelattribute() got an unexpected keyword argument 'koerperhaelfte'. Signature: `_value_1: ANY[]`

---

EDIT:

I try to create SOAP envelope by hand. If I set :

....
<hilfsmittelattribute>
    <koerperhaelfte>5</koerperhaelfte>
</hilfsmittelattribute>
....

It actually works... So the problem needs to be in Zeep on handling Any type.

If anyone has still trouble with this...

The fix is to create custom etree element

import lxml.etree as ET
koerperhaelfte_element = ET.Element("koerperhaelfte")
koerperhaelfte_element.text = "rechts"

and then use it inside json

'hilfsmittelattribute': {
      "_value_1": [koerperhaelfte_element],
},
