The server uses Firestore as the backend. Kindly let me know how to fix this.

Even though this is a different backtrace, it may be the same underlying issue as #29353.

@nodejs/http2

[mcollina]

@jsloop42 would you mind to add a way to reproduce this crash?

Could you try using Node 10 and see if the issue persists?

[addaleax]

@mscdex That’s pretty unlikely, but it was probably also introduced in the v8.x backport of 8a4a193.

Please find the code that produces the crash.

public async checkForDuplicatePosts(body: string, postId: string): Promise<Post[]> {
    let xs = await this.fsDB.collection(Collection.Posts).get().then(xs => xs).catch(err => []);  // Fetches the entire collection
    let dupList: Post[] = [];
    xs.forEach(function(doc) {
        let post = doc.data();
        if (post["postId"] != postId && Utils.isDuplicatePost(body, post)) {  // runs string similarity algorithm
            dupList.push(ModelUtils.getPostFromData(post));  // converts the DocumentData to Entity object
        }
    });
    return dupList;
}

This crashes even if I fetch the collection with pagination and runs the string similarity algorithm on it.

---

Since I am using Firebase as the deployment target, the node version I am having to use is v8 as the environment does not support other versions as of now.

[addaleax]

I’ve looked into this, but with the limited information available, I’d say either this is also addressed by #29399, or we need more information (e.g. a reproduction, a core dump, etc.).

[ghost]

Please find the debug log.

@jsloop42 Thanks, but a reproduction or a core dump or something along those lines would really be more helpful. The npm debug log doesn’t really say more than that there was an error.

I'm still having a similar problem when receiving a lot of messages from @google-cloud/pubsub.
I'm on 8.16.2 and can reproduce fairly easily.

[dobromyslov]

I have same crash when use pubsub subscription.

[dobromyslov]

Updated to 10.18.0. Everything is ok there. But Node 10 is Beta in Google Cloud Functions.

[BridgeAR]

@dobromyslov thanks for your confirmation.

Node.js v8.x is end-of-life and won't receive any fixes anymore. I am closing this, since the issue seems to be specific about v8.x. If it does happen on any other release line, please leave a comment so that this is reopened.
