Solve the following python programming problem given the following code:
def handle_module_upgrade_request(controller, module_id, pipeline) : 
    from vistrails.core.modules.module_descriptor import ModuleDescriptor 
    from vistrails.core.upgradeworkflow import UpgradeWorkflowHandler, UpgradePackageRemap, UpgradeModuleRemap 
    from vistrails.core.modules.basic_modules import identifier as basic_pkg 
    def remap_functions(old_module, new_module, function_remap) : 
        use_registry = True 
        function_ops = [] 
        for function in old_module.functions : 
            if (function.name in function_remap) : 
                remap = function_remap [function.name] 
                if (remap is None) : 
                    continue 
else : 
                    if (not isinstance (remap, basestring)) : 
                        function_ops.extend (remap (function, new_module)) 
                        continue 
else : 
                        function_name = remap 
if (len (function.parameters) > 0) : 
                    (new_param_vals, aliases) = zip (* [(p.strValue, p.alias) for p in function.parameters]) 
else : 
                    new_param_vals = [] 
                    aliases = [] 
if use_registry : 
                    function_port_spec = function_name 
else : 
                    def mk_psi(pos) : 
                        psi = PortSpecItem (module = 'Module', package = basic_pkg, namespace = '', pos = pos) 
                        return psi

                new_module.add_function (new_function) 
if (None in function_remap) : 
            remap = function_remap [None] 
            function_ops.extend (remap (None, new_module)) 
return function_ops 
def remap_dst_connections(old_module, new_module, port_remap) : 
        use_registry = True 
        create_new_connection =...

    
    

    Fix the buggy line: return UpgradeWorkflowHandler.remap_module (insert_vis, module_id, pipeline, remap)

#Here is Python program to fix the buggy line: return UpgradeWorkflowHandler.

return UpgradeWorkflowHandler.remap_module (controller, module_id, pipeline, remap)
