IO Exception: input contained no data

Hello everybody,

I've used WSDL2APEX to create my apex class from wsdl which is shared to me. At first the wsdl included soap 1.1 and 1.2 together but to be able to generate the class I removed multi binding, port etc. After doing some development, when I tried to trigger the 'invoke(...)' method I face 
IO Exception: input contained no data error. When I try same request on soap ui with the data from salesforce I got, it returns success. Anyone got ideas for the solution?
P.S. I did not involved in the development of the web service which I tried to send request.
