The service returns different responses to the same request, in no particular order.

Example service:

# -*- coding: utf-8 -*-

from spyne import Application, rpc, ServiceBase
from spyne.protocol.soap import Soap11
from spyne.server.wsgi import WsgiApplication
from spyne.model.primitive import String
from spyne.model.complex import ComplexModel

class ErrorType(ComplexModel):

    __namespace__ = "other.ns"

    errorCode = String.customize(sub_ns="other.ns")

class PortType(ServiceBase):

    @rpc(_returns = [ErrorType.customize()])
    def test(ctx):
        return ErrorType(errorCode="code")

app = Application([PortType], tns="target.ns", in_protocol=Soap11(validator="soft"), out_protocol=Soap11())
application=WsgiApplication(app)

Request:

<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
    <Body>
        <test xmlns="target.ns"/>
    </Body>
</Envelope>

Response:

<?xml version="1.0" encoding="UTF-8"?>
<soap11env:Envelope xmlns:s0="other.ns" xmlns:soap11env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="target.ns">
    <soap11env:Body>
        <tns:testResponse>
            <tns:testResult0>
                <s0:errorCode>code</s0:errorCode>
            </tns:testResult0>
        </tns:testResponse>
    </soap11env:Body>
</soap11env:Envelope>

or

<?xml version="1.0" encoding="UTF-8"?>
<soap11env:Envelope xmlns:soap11env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tns="target.ns">
    <soap11env:Body>
        <tns:testResponse>
            <tns:testResult0>
                <ns0:errorCode xmlns:ns0="other.ns">code</ns0:errorCode>
            </tns:testResult0>
        </tns:testResponse>
    </soap11env:Body>
</soap11env:Envelope>

Why is that?
How to avoid this?

Can you add the missing bits and fix the formatting as well?

Both xml documents are equivalent, so any SOAP client should properly parse both documents.

That said, I can't see how the same server could produce different outputs randomly like this. Are you sure nothing is different between the servers that produce these two responses?

I understand that the answers are equivalent.
But I met a client for whom these are different answers.

I noticed a feature.
This situation is reproduced only when the script is run through an external uwsgi server.
Through the built-in
from wsgiref.simple_server import make_server
it does not repeat itself.

this is outside of scope of this project. xml canonicalization should be made in an after_serialize hook
