getReplica not emit correctly the event

Node.js SDK
,
1

Hi, I find that the getReplica function from collection.js not trigger correctly the replica and end events. So the Promise remain unresolved.

This happend to me on NODE sdk 3.2. Is that fixed on other version ?

Based on basic nodejs event:

const EventEmitter = require(‘events’);
const myEE = new EventEmitter();

myEE.on(“x”, () => console.log(“x”));
myEE.emit(“y”);

myEE.on(“y”, () => console.log(“y”));
myEE.emit(“x”);

myEE.emit(“asdf”);

our bind events from super callback should be trigger before callback in order to be able to listed on that events

class StreamableRowPromise extends StreamablePromise {
constructor(fn) {
let err;
const rows = ;
let meta;
let resolverFn, rejectFn;
super((emitter, resolve, reject) => {
resolverFn = resolve;
rejectFn = reject;
});

    this.on('row', (r) => rows.push(r));
    this.on('meta', (m) => (meta = m));
    this.on('error', (e) => (err = e));
    this.on('end', () => {
        if (err && rejectFn) {
            return rejectFn(err);
        }
        resolverFn && resolverFn(fn(rows, meta));
    });
}

}

Hey @laurentiustroia!

Have you tried using the Node.js SDK v4.1.0? That is the most current version and may fix your issue, but if not let us know and we’ll investigate further!

Cheers

What version of Node are you running? If you are on 17.x can you try 16.x and see if the issue goes away?

Thanks

Hi @laurentiustroia

It looks like you might be hitting Loading.... More importantly, get replica is not yet supported in 4.0 Loading...
