Solve the following python programming problem given the following code:
def apply_layout(self, layout_profile) : 
    if self.env.settings.get ('debug_autolayout') : 
        layout_metadata = self.env.settings.get (layout_profile, { 
            
}) 
        layout = layout_metadata.get ('layout', None) 
        if layout : 
            self.w.set_layout (layout) 
            def apply_tool_layout(tool) : 
                g = layout_metadata.get (tool.name, None) 
                if (g is not None) : 
                    v = (tool.v if (tool.v is not None) else tool._mk_v ()) 
                    self.w.set_view_index (v, g, 0) 
else : 
                    if (tool.v is not None) : 
                        self.w.focus_view (tool.v) 
                        self.w.run_command ('close_file') 
else : 
                        pass 
apply_tool_layout (self.env.stack) 
            apply_tool_layout (layout_metadata.env.watches) 
            apply_tool_layout (self.env.output) 

    
    

    Fix the buggy line: apply_tool_layout (layout_metadata.env.watches)
