AssertionError [proxy.py]

Hi!!

I'm using:

• Python 3.7.2
• robotframework-sudslibrary-aljcalandra==1.1

My Robot code:

Enviar requisição SOAP
    Create Soap Client      ${WSDL_URL}
    ${MESSAGE}      Get File    consultaProcesso_envio.xml
    ${MESSAGE}      Create Raw Soap Message    ${MESSAGE}
    Log   ${MESSAGE}
    ${RESPONSE}    Call Soap Method      consultarProcesso    ${MESSAGE}
    ${RESPONSE_XML}         Get Last Received

When i have tried to execute then, the following error occurs in Call Soap Method:

  File "c:\users\mayara.fernandes\appdata\local\programs\python\python37-32\lib\site-packages\SudsLibrary\proxy.py", line 46, in call_soap_method
    return self._call(None, None, False, name, *args)
  File "c:\users\mayara.fernandes\appdata\local\programs\python\python37-32\lib\site-packages\SudsLibrary\proxy.py", line 105, in _call
    received = method(__inject={'msg': args[0].message})
  File "c:\users\mayara.fernandes\appdata\local\programs\python\python37-32\lib\site-packages\suds\client.py", line 521, in __call__
    return client.invoke(args, kwargs)
  File "c:\users\mayara.fernandes\appdata\local\programs\python\python37-32\lib\site-packages\suds\client.py", line 761, in invoke
    assert msg.__class__ is suds.byte_str_class

I solved the problem by making an adjustment in proxy.py:

Original Code:

            if len(args) == 1 and isinstance(args[0], RawSoapMessage):
                received = method(__inject={'msg': args[0].message})

Code with my adjustment:

            if len(args) == 1 and isinstance(args[0], RawSoapMessage):
                message = byte_str(args[0].message)
                received = method(__inject={'msg': message})

Could you evaluate this adjustment, was it the best way to solve it?

Thanks. May Fernandes

So you converted the message into bytes and then passed it?

Yes.

Darn doesn't work for me!

Hi I tried your solution but get message NameError: name 'byte_str' is not defined

Do I need more ?

@bruindav I received same error as you did. I then used the .encode() rather to encode string to bytes as per below: if len(args) == 1 and isinstance(args[0], RawSoapMessage): message = args[0].message.encode()
received = method(__inject={'msg': message})

Then in robot framework I had to decode the response as

${sendmessage}    Call Soap Method    *YourServiceMethod*    ${message}
${checkresponse}    Get Last Received
${checkresponseDecoded}    Decode Bytes To String    ${checkresponse}    UTF-8

This worked for me
