I too had the same error in trace logs. My newly created function in API was throwing the same error but to my surprise, the old functions were performing good. The issue was - My contract data members had few variables of type object. soap-xml was not able to handle it well, however, I can see that array of object types (object[]) were getting passed without any issues. Only a simple object type was not getting parsed by soap. This could be one more reason why the services throw the above error.
