The following is the result of calling "cluster nodes" in my cluster in 2 moments:
Shouldn't the "connectToNodesOfCluster" function be like this? (refer to the FIXME comments below)
function connectToNodesOfCluster (firstLink, callback) {
var redisLinks = [];
var fireStarter = connectToLink(firstLink);
fireStarter.cluster('nodes', function(err, nodes) {
if (err) {
callback(err, null);
return;
}
var lines = nodes.split('\n');
var n = lines.length -1;
while (n--) {
var items = lines[n].split(' ');
var name = items[0];
var flags = items[2];
var link = ( flags === 'myself' || flags === 'myself,master') ? firstLink : items[1];
var linkState = items[7]; // FIXME: this index was incremented;
if (lines.length === 1 && lines[1] === '') {
var slots = [0, 16383]
} else {
var slots = items[8].split('-'); // FIXME: this index was also incremented;
}
console.log(linkState);
if (linkState === 'connected') {
redisLinks.push({name: name, link: connectToLink(link), slots: slots});
}
if (n === 0) {
console.log(redisLinks);
callback(err, redisLinks);
}
}
});
}
In both of these moments, the same error occurred. Please, can you help me with that?

Hi, João, I am trying to connect to a redis cluster (version 2.9.11) and I have the following error:
