Connecting Matlab and Sharepoint using WSDL

I'm trying to connect Matlab and MS SharePoint using WSDL. Here's some code connecting to a random WSDL-webservice:

wsdl_link = 'http://www.webservicex.com/globalweather.asmx?wsdl';
matlab.wsdl.setWSDLToolPath('JDK',jdk_path,'CXF',cxf_path)
matlab.wsdl.createWSDLClient(wsdl_link);

This works fine.

Now I want to connect to my companies SharePoint service. For this I change the wsdl link to

wsdl_link = 'https://my-company.osram.com/content/10003824/_vti_bin/lists.asmx?wsdl';

At this point I had some problems with certificates ('https'), but I'm pretty sure that I got ride of these problems. But the code is not working. The long-ish error starts with

Error using
matlab.wsdl.createWSDLClient>extractTypeFromSchemaElement
(line 917)
The element 'GetListResult' in
'schema' is defined with an
anonymous complex type, which is not
supported. Edit the schema to use a
named type.

Now the question: Is this a Matlab problem or a SharePoint problem or a problem with our SharePoint implementation?

I'm triyng to access Sharepoint data via Matlab too and I have the same Warning (strangely not error) when creating the WSDL client:

Warning: The element 'GetWebCollectionResult' in 'schema' is defined with an anonymous complex type, which is not supported.  References to 'GetWebCollectionResult' may
generate errors.  Edit the schema to use a named type.

Using Matlab R2018b, my code is:

% WSDL paths setup
jdk='C:\Program Files\Java\jdk1.8.0_191';
cxf='C:\apache-cxf-3.2.7';
matlab.wsdl.setWSDLToolPath('JDK',jdk,'CXF',cxf);

% Sharepoint web service name
webservicename='Webs';

% My company
sharepoint_url= ['http://MY_COMPANY_SHAREPOINT_URL.org/_vti_bin/' webservicename '.asmx?wsdl'];

% Creating WSDL client
wsdl_obj = matlab.wsdl.createWSDLClient(sharepoint_url);

% Add *.jar creted by the client to java dynamic path
javaaddpath(['.\+wsdl\' webservicename '.jar']);

%display WebService characteristics
