How to include multiple occuring elements of complext type into the soap response

[sighoya]

My example:

from spyne import (
    Application, ServiceBase, rpc, XmlAttribute
)
from spyne.protocol.soap import Soap11
from wsgiref.simple_server import make_server
from spyne.model import Integer
from spyne.model import Long
from spyne.model import Unicode
from spyne.model import Enum
from spyne.model import ComplexModel
from spyne.util.wsgi_wrapper import WsgiMounter
import logging

IssueServiceName= 'IssueService'
IssueServicePort= 8080

logging.basicConfig(level=logging.INFO)
logging.getLogger("spyne.protocol.xml").setLevel(logging.DEBUG)


class GetIssueRequest(ComplexModel):
    issueIds = Long(sub_name='Id',min_occurs=0,max_occurs='unbounded')

class Issue(ComplexModel):
    issueId=XmlAttribute(Long(sub_name="Id"),use="required")
    title=Unicode
    type=Enum("Bug","Task","Story",sub_name="Type",type_name="Type")


class GetIssueResponse(ComplexModel):
    issues = Issue.customize(minOccurs="0", maxOccurs="unbounded",sub_name="Issue")
    numberOfIssues=Integer(sub_name="NumberOfIssues")

class IssueService(ServiceBase):
    @rpc(GetIssueRequest,_operation_name="GetIssueRequest",_returns=GetIssueResponse,_body_style='bare')
    def getIssue(ctx,request):
        getIssueResponseDict = {
            "issues": [Issue(issueId=issueId,
                             title=f"issue-{issueId}",
                             Type="Task")  for issueId in request.issueIds],
            "NumberOfIssues": len(request.issueIds)
        }

        return GetIssueResponse(**getIssueResponseDict)


issueApplication = Application(
    [IssueService],
"abc",
    in_protocol=Soap11(validator='soft',pretty_print=True),
    out_protocol=Soap11(validator='soft',pretty_print=True)
)
def renameNamspaces(namepsace2ValueMap, namespace2namespaceMap):
    for sourceNamespace,targetNamespace in namespace2namespaceMap.items():
        namepsace2ValueMap[targetNamespace]=namepsace2ValueMap[sourceNamespace]
        del(namepsace2ValueMap[sourceNamespace])



renameNamspaces(issueApplication.interface.nsmap,{'soap11env':'SOAP-ENV','tns':'ns1'})
rootApplication = WsgiMounter({IssueServiceName:issueApplication})

if __name__ == "__main__":
    logging.info(f"Listening to http://127.0.0.1:{IssueServicePort}")
    logging.info(f"WSDL is at: http://127.0.0.1:{IssueServicePort}/{IssueServiceName}?wsdl")
    server = make_server("127.0.0.1", IssueServicePort, rootApplication)
    server.serve_forever()

Given the request:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body xmlns:ns1="abc">
        <GetIssueRequest>
            <Id>0</Id>
            <Id>1</Id>
            <Id>2</Id>
        </GetIssueRequest>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

I would like to receive:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body xmlns:ns1="abc">
        <GetIssueResponse>
            <Issue id="0">
              <title>issue-0</title>
              <type>task</type>
            </Issue>
            <Issue id="1">
              <title>issue-1</title>
              <type>task</type>
            </Issue>
            <Issue id="2">
               <title>issue-2</title>
              <type>task</type>
            </Issue>
        </GetIssueResponse>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Issueing the request yields:

TypeError: int() argument must be a string, a bytes-like object or a real number, not 'Issue'

It seems that the serializer is assuming the issue would begin with an attribute id, just my assumption.

What I'm doing wrong?

Environment is:

Python 3.10 
spyne==2.13.16

Gosh, changing maxOccurs -> max_occcurs resolved it, likewise for min_occurs.
