Solve the following python programming problem given the following code:
def __call__(self, environ, start_response) : 
    _tls.current_session = Session (lifetime = self.lifetime, no_datastore = self.no_datastore, cookie_only_threshold = self.cookie_only_thresh, cookie_key = my_start_response.cookie_key) 
    def my_start_response(status, headers, exc_info = None) : 
        try : 
            _tls.current_session.save () 
except ValueError : 
            _tls.current_session.clear () 
for ch in _tls.current_session.make_cookie_headers () : 
            headers.append (('Set-Cookie', ch)) 
return start_response (status, headers, exc_info) 
return self.app (environ, my_start_response) 

    
    

    Fix the buggy line: _tls.current_session = Session (lifetime = self.lifetime, no_datastore = self.no_datastore, cookie_only_threshold = self.cookie_only_thresh, cookie_key = my_start_response.cookie_key)

#Here is Python code to fix the buggy line: _tls.

_tls.current_session = Session (lifetime = self.lifetime, no_datastore = self.no_datastore, cookie_only_threshold = self.cookie_only_thresh, cookie_key = self.cookie_key)
