Unable to attach xml file to message

[mikeinottawa]

I'm unable to attach a xml file in the zeep message. Code is below. The error I get is 'string indices must be integers'

I'm not a python developer by trade so please excuse the poor python (great language) below, or any common mistake I have made.

Thank you community :)

import PySimpleGUI as sg
import base64
from zeep import Client, Settings, xsd
from zeep.cache import SqliteCache
from zeep.transports import Transport

sg.theme('Dark Blue 3')

layout = [  [ sg.Text('XML REQUEST FILE:')],
            [ sg.Input(key='XML'), sg.FileBrowse() ],             
            [ sg.Text('WSDL INPUT:')],
            [ sg.Input(key="WSDL_LOC"), sg.FileBrowse()],
            [ sg.Text('SERVICE LOCATION:')],
            [ sg.InputText(key='SERVICE_LOCATION')],
            [ sg.Ok('Submit Request') ],
            [ sg.Output(size=(80,20)) ] ] 


window = sg.Window('-- SOAP CLIENT -- ', layout)

while True:
    event, values = window.Read()

    if event is 'Submit Request':
        settings = Settings(strict=True, xml_huge_tree=True )
        transport = Transport(cache=SqliteCache())
       
        values['WSDL_LOC'] = 'http://localhost:31656/Sample.asmx?WSDL'
        values['XML'] = 'Sample.xml'        
        values['SERVICE_LOCATION'] = 'http://localhost:31656/example.asmx?op=submit'

        client = Client(values['WSDL_LOC'], settings=settings, transport=transport)

        with open(values['XML'], "b") as f:
            byte = f.read()
            
        print(type(byte)) #<byte>

        try:
             client.service.sampleSubmit(byte)
        except Exception as ex:
            print(ex)
        
        continue;

    if event is None:
        break;
    
    print(event, values); 
```

Typically a service would take named parameters matching what that service. The byte is unlikely to be a valid name as it's not a string. Setting that byte to the correct parameter could be your way forward, but I assume you have progressed already.
