Solve the following python programming problem given the following code:
@ Text ('announce eor') 
def announce_eor(self, reactor, service, command) : 
    def callback(self, command, peers) : 
        family = self.parser.api_eor (command) 
        if (not family) : 
            self.log_failure (('Command could not parse eor : %s' % command)) 
            reactor.answer (service, 'error') 
            (yield True) 
            return 
reactor.configuration.inject_eor (peers, family) 
        self.log_message (('Sent to %s : %s' % ((', '.join ((peers if peers else [])) if (peers is not None) else 'all peers'), family.extensive ()))) 
        (yield False) 
        reactor.route_update = True 
        reactor.answer (service, 'done') 
try : 
        (descriptions, command) = self.parser.extract_neighbors (command) 
        peers = reactor.match_neighbors (descriptions) 
        if (not peers) : 
            self.log_failure (('no neighbor matching the command : %s' % callback), 'warning') 
            reactor.answer (service, 'error') 
            return False 
reactor.plan (callback (self, command, peers), 'announce_eor') 
        return True 
except ValueError : 
        self.log_failure ('issue parsing the command') 
        reactor.answer (service, 'error') 
        return False 
except IndexError : 
        self.log_failure ('issue parsing the command') 
        reactor.answer (service, 'error') 
        return False 

    
    

    Fix the buggy line: self.log_failure (('no neighbor matching the command : %s' % callback), 'warning')

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

self.log_failure (('no neighbor matching the command : %s' % command), 'warning')
