Node-redis: Uncaught exception: TypeError: Cannot read property 'code' of null at Object.redis.createClient.retry_strategy

var client = redis.createClient({
    retry_strategy: function (options) {
        if (options.error.code === 'ECONNREFUSED') {
            // End reconnecting on a specific error and flush all commands with a individual error
            return new Error('The server refused the connection');
        }
        if (options.total_retry_time > 1000 * 60 * 60) {
            // End reconnecting after a specific timeout and flush all commands with a individual error
            return new Error('Retry time exhausted');
        }
        if (options.times_connected > 10) {
            // End reconnecting with built in error
            return undefined;
        }
        // reconnect after
        return Math.max(options.attempt * 100, 3000);
    }
});

throw exception:

Uncaught exception:  TypeError: Cannot read property 'code' of null     at Object.redis.createClient.retry_strategy 

log out options:

{ 
  attempt: 1,
  error: null,
  total_retry_time: 0,
  times_connected: 1
 }

I'm also trying to use the retry_strategy, even as minimal as

        retry_strategy: function (options) {
                console.log(options);
                // reconnect after
                return 10000;
            }

seems not to work, my process is crashing like that:

 AbortError: Redis connection lost and command aborted. It might have been processed.
