MongoDB Error: "MongoServerClosedError: Server is closed"

Project id: 8b67ba4d-ba67-4f38-97ef-8caab4e245fe Hi folks, my express server has trouble connecting to my mongo service on startup. It was functioning with a mongodb plugin until a couple weeks ago. I thought maybe I'll try switching to a mongodb image-based service in case it magically starts working. But the exact same error. WOuld appreciate some insight, thank you!

Solution:

The test script was trying to connect and close at the same time

looking

BenIsenstein•14mo ago

Thanks Brody 🙂

Brody•14mo ago

can you please try setting this https://mongodb.github.io/node-mongodb-native/4.11/interfaces/MongoOptions.html#connectTimeoutMS to a higher value like 10000?

BenIsenstein•14mo ago

SUre, it's a part of the Client options object?

Brody•14mo ago

looks to be, yeah

BenIsenstein•14mo ago

pushed to my repo, let's monitor the deployment

Brody•14mo ago

you tell me what happens, i cant monitor anything lol

BenIsenstein•14mo ago

lol I figured I was giving you implicit consent to observe my project infra

Brody•14mo ago

dont work for railway so i cant see anything

BenIsenstein•14mo ago

Oh I thought you worked for them! What's your relation to them/how did you end up being a conductor?

Brody•14mo ago

i help so they gave me cool role

BenIsenstein•14mo ago

BenIsenstein•14mo ago

alright still a failed health check after 10s

Brody•14mo ago

what do the deployment logs look like?

BenIsenstein•14mo ago

No description

Brody•14mo ago

that doesnt look like there was even a connection attempt?

BenIsenstein•14mo ago

So I'm trying to synchronously fetch the Google OAuth refresh tokens before the connection is established Kay let me dig to the. bottom

Brody•14mo ago

keep me updated

BenIsenstein•14mo ago

If you want to look in my repo the file is /repositories/mongo Some background I run many one-time mongo operations inside of a wrapper function called "withConnectAndClose()"

export const withConnectAndClose = async <
    TDocument,
    TReturn
>(
    db: string,
    collection: string,
    callback: (col: Collection<TDocument>) => Promise<TReturn>
) => {
    try {
        let returnVal: TReturn

        await mongoClient.connect()
        returnVal = await callback(mongoClient.db(db).collection(collection))
        await mongoClient.close()

        return returnVal
    } catch (error) {
        await mongoClient.close()
        throw new Error(error)
    }
}

export const withConnectAndClose = async <
    TDocument,
    TReturn
>(
    db: string,
    collection: string,
    callback: (col: Collection<TDocument>) => Promise<TReturn>
) => {
    try {
        let returnVal: TReturn

        await mongoClient.connect()
        returnVal = await callback(mongoClient.db(db).collection(collection))
        await mongoClient.close()

        return returnVal
    } catch (error) {
        await mongoClient.close()
        throw new Error(error)
    }
}

Brody•14mo ago

looks good to me

BenIsenstein•14mo ago

my entry file for the project starts by running a function "initGoogleApi()"

require("dotenv").config()
import { existsSync } from 'fs'
import createError from 'http-errors'
import express from 'express'
import cookieParser from 'cookie-parser'
import logger from 'morgan'
import apiRouter from './routes/apiRouter'
import { startJobs } from './cron'

require('./helpers').initGoogleApi().then(() => {
  const app = express()
  ...
})

require("dotenv").config()
import { existsSync } from 'fs'
import createError from 'http-errors'
import express from 'express'
import cookieParser from 'cookie-parser'
import logger from 'morgan'
import apiRouter from './routes/apiRouter'
import { startJobs } from './cron'

require('./helpers').initGoogleApi().then(() => {
  const app = express()
  ...
})

Brody•14mo ago

little tip, wrap your code in triple back ticks

BenIsenstein•14mo ago

That initGoogleApi() function is warpped with withConnectAndClose()

import { writeFileSync } from 'fs'
import { oauth2Client, google } from '../repositories'
import { getGoogleTokens } from '../services'
import { USER_ID } from '../values'

export const initGoogleApi = async () => {
    oauth2Client.setCredentials(await getGoogleTokens(USER_ID))
    google.options({
        auth: oauth2Client
    })
    writeFileSync(
        `${__dirname}/../credentials/articles-service-account-credentials.json`,
        process.env.ARTICLES_SERVICE_ACCOUNT_CREDENTIALS
    )
    writeFileSync(
        `${__dirname}/../credentials/cloud-tasks-client-account-credentials.json`,
        process.env.CLOUD_TASKS_CLIENT_ACCOUNT_CREDENTIALS
    )
}

import { writeFileSync } from 'fs'
import { oauth2Client, google } from '../repositories'
import { getGoogleTokens } from '../services'
import { USER_ID } from '../values'

export const initGoogleApi = async () => {
    oauth2Client.setCredentials(await getGoogleTokens(USER_ID))
    google.options({
        auth: oauth2Client
    })
    writeFileSync(
        `${__dirname}/../credentials/articles-service-account-credentials.json`,
        process.env.ARTICLES_SERVICE_ACCOUNT_CREDENTIALS
    )
    writeFileSync(
        `${__dirname}/../credentials/cloud-tasks-client-account-credentials.json`,
        process.env.CLOUD_TASKS_CLIENT_ACCOUNT_CREDENTIALS
    )
}

Brody•14mo ago

all looks good to me, though keep in mind im not a js/ts dev

BenIsenstein•14mo ago

fair enough And this was working seamlessly for close to a year...

Brody•14mo ago

updated any deps recently? are you using private networking?

BenIsenstein•14mo ago

Private networking needs to be set correct? I haven't manually set it to private This exact issue was happening with the mongodb plugin before So not a networking issue I believe No deps updated

Brody•14mo ago

but are you actively utilizing the private networking?

BenIsenstein•14mo ago

Is private networking active by default? I just started this project from a template and haven't made any networking adjustements manually

Brody•14mo ago

its on by default, but im asking if you use it

BenIsenstein•14mo ago

Not actively using it

Brody•14mo ago

disable it

BenIsenstein•14mo ago

Sure most recent deploy logs:

Brody•14mo ago

okay let me know if anything improves with private networking disabled

BenIsenstein•14mo ago

Currently building What's your background? Thakns for being so helpful btw 🙂

Brody•14mo ago

i have no background, in tech at least last job was a landscaper

BenIsenstein•14mo ago

lol that counts How did you get involved in techy stuff?

Brody•14mo ago

uh id probably say arduino

BenIsenstein•14mo ago

Nice! Okay so interesting now Several errors in order:

Brody•14mo ago

you can connect to mongo from something like dbgate right?

BenIsenstein•14mo ago

I think so

Brody•14mo ago

check again i have to go do some plumbing, ill be back in a bit

BenIsenstein•14mo ago

I'm gonna go at this from scratch again, removing everything but the google init and logging everywhere all good, see ya!

jr•14mo ago

What did it end up being? Did it just work after disabling the private network?

BenIsenstein•14mo ago

No So, I had another module trying to run a test script on import. -_-

Solution

BenIsenstein•14mo ago

The test script was trying to connect and close at the same time

BenIsenstein•14mo ago

Just forgot to comment it out once I was done with local testing How can I mark this solved?

Brody•14mo ago

glad you've solved it!
