Solve the following python programming problem given the following code:
@ logging.log_task_wrapper (LOG.info, _ ('Exit context: `custom_image`')) 
def cleanup(self) : 
    'Delete created custom image(s).' 
    if ('admin' in self.context) : 
        user = self.context ['users'] [0] 
        tenant = self.context ['tenants'] [user ['tenant_id']] 
        if ('custom_image' in tenant) : 
            self.delete_one_image (user, self ['custom_image']) 
            tenant.pop ('custom_image') 
else : 
        def publish(queue) : 
            users = self.context.get ('users', []) 
            for (user, tenant_id) in utils.iterate_per_tenants (users) : 
                queue.append ((user, tenant_id)) 
def consume(cache, args) : 
            (user, tenant_id) = args 
            tenant = self.context ['tenants'] [tenant_id] 
            if ('custom_image' in tenant) : 
                self.delete_one_image (user, tenant ['custom_image']) 
                tenant.pop ('custom_image') 
broker.run (publish, consume, self.config ['workers']) 

    
    

    Fix the buggy line: self.delete_one_image (user, self ['custom_image'])

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

self.delete_one_image (user, tenant ['custom_image'])
