Solve the following python programming problem given the following code:
def _get_options(self, kind, module_name) : 
    'Options dictionary for the corresponding app.' 
    configs = [config for config in self.config.get (kind, []) if (module_name in config.get ('modules', []))] 
    if (len (configs) == 1) : 
        config = configs [0] 
        def letters_generator(modules) : 
            for letters in map (set, zip (* modules)) : 
                if (len (letters) == 1) : 
                    (yield letters.pop ()) 
else : 
                    return 
name = ''.join (letters_generator (config ['modules'])).rstrip ('.') 
        return (name, config) 
else : 
        if (len (configs) > 1) : 
            raise KitError (('Duplicate %s for module %r found.' % (kind, module_name))) 
else : 
            raise KitError (('Undefined %s for module  %r.' % (configs, module_name))) 

    
    

    Fix the buggy line: raise KitError (('Undefined %s for module  %r.' % (configs, module_name)))

#Here is Python code to fix the buggy line: raise KitError (('Undefined %s for module  %r.

raise KitError (('Undefined %s for module  %r.' % (kind, module_name)))
