Hi @masx200_masx200,

Thanks for reporting this issue. This was also raised on NODE-2536, and a fix has been committed. This will be available in the next release of MongoDB Node.js driver (v3.5.7).

Regards,
Wan.

exact same problem so, how can i fix it, and fix mongoDB version is already released or not?
mongoose version 5.9.13 and mongoDB atlas 4.2.6, Node.js v 14.2.0
with these dependencies the same error is showing again

wan · May 13, 2020, 2:01am

Hi @Koushik_Saha, welcome!

MongoDB Node.js driver version 3.5.7 that contains the fix has been released. Based on my test, I can confirmed that this version removed the warnings for circular dependencies.

Looking at mongoose v5.9.13 package.json, it is importing the correct driver version. Also, based on a quick test with mongoose v5.9.13 and node v14.2.0 it is working correctly for me.

As the warning message suggested, could you execute with node --trace-warnings to show where the exact warning was created and post the trace ?

Also, ensure within your node_modules that you have the correct version of the driver v3.5.7. If you’re still encountering the issue, please provide how you’re triggering these warning messages.

Regards,
Wan.

It shows that after run ‘node --inspect --trace-warnings’ and require(mongodb)
But all the errors are same:

Hi @Koushik_Saha,

Please check the version of MongoDB Node.js driver (mongodb) being referenced in the project. For example, within node_modules/mongodb/package.json make sure that the version of mongodb package is greater than or equal to 3.5.7.

If you’re using an older version, you could run npm update mongodb to update the package.

Regards,
Wan.

Koushik_Saha · May 31, 2020, 8:27am

Sir,
i use these packages on my project mongoose v3.5.8 and mongoose works behind with mongodb package v3.5.7

“dependencies”: {
“@sendgrid/mail”: “^7.1.1”,
“async”: “^3.2.0”,
“bad-words”: “^3.0.3”,
“bcryptjs”: “^2.4.3”,
“connect-mongo”: “^3.2.0”,
“cookie-parser”: “^1.4.5”,
“dotenv”: “^8.2.0”,
“ejs”: “^3.1.3”,
“express”: “^4.17.1”,
“express-session”: “^1.17.1”,
“lodash”: “^4.17.15”,
“method-override”: “^3.0.0”,
“mongoose”: “^5.9.16”,
“multer”: “^1.4.2”,
“socket.io”: “^2.3.0”
}

I waste your so many times but i don’t know how to fix it. i removed node_modules file then run “npm i” but that not work ether. so, what do i do?
That’s the mongoose package.json in node_modules file.–>

“dependencies”: {
“bson”: “^1.1.4”,
“kareem”: “2.3.1”,
“mongodb”: “3.5.7”,
“mongoose-legacy-pluralize”: “1.0.2”,
“mpath”: “0.7.0”,

“sliced”: “1.0.1”
}

wan · June 2, 2020, 7:23am

Hi @Koushik_Saha,

Unfortunately I’m unable to reproduce the issue you’re seeing. I copied the dependencies above into package.json, executed npm install with node version 14.3.0 and inspection of mongodb package is as expected.

Could you provide the output of :

npm list mongodb
npm list -g mongodb

Also, do you have any other node_modules within your application project ?

Regards,
Wan.

Koushik_Saha · June 4, 2020, 12:16pm

Sir, These are commands you want me to run.
& i think connect-mongo is the problem right?
If it is what do i do. Because connect mongo v3.2.0 is latest and that uses v3.5.5 mongodb driver not latest one.

PS D:\PlayGround\Social.Forum> npm list mongodb
social.forum@1.0.1 D:\PlayGround\Social.Forum
±- connect-mongo@3.2.0
| -- mongodb@3.5.5 – mongoose@5.9.16
`-- mongodb@3.5.7

PS D:\PlayGround\Social.Forum> npm list -g mongodb
C:\Users\SHARK\AppData\Roaming\npm
`-- (empty)

wan · June 5, 2020, 2:50am

Hi @Koushik_Saha,

That’s correct, in your project connect-mongo package depends on mongodb package version 3.5.5. You should update the mongodb package that is referenced as a dependency by connect-mongo. You could try to uninstall and re-install back connect-mongo package.

Note that connect-mongo v3.2.0 requirement for mongodb is "^3.1.0", which means you should be able to use the latest stable version of mongodb package. For example, the result of my npm list mongodb :

appName@1.0.0 /path/to/appName

├─┬ connect-mongo@3.2.0
│ └── mongodb@3.5.8 
└─┬ mongoose@5.9.16
  └── mongodb@3.5.7

Regards,
Wan.

Koushik_Saha · June 5, 2020, 7:04pm

Sir, its done
No error is showing up now.
& sir this is the 1st project (node, mongodb etc.) that i’m working on for IGNOU BCA 6th Sem.
Sir if you have some time just check this and let me know something is wrong or not.
i used some github projects and merge & change some thing.

Hi @Koushik_Saha,

I’m glad that you have managed to solve the dependency problem.

Well done on your first MongoDB/Node project. If you would like to learn more about Node.JS and MongoDB, I’d recommend to enrol in M220JS: MongoDB for JavaScript Developers a free online course from MongoDB University.

If you have any questions, please open a new discussion thread with the relevant information.

Best regards,
Wan.

Sir,
actually i thought the if the error was gone everything was all right but no, the session was saved when any one signed in on the site but now after sign in sometime later account automatically signed up but giving an error but the code was same from the beginning i never faced that problem before and maybe the problem is connect-mongo package. how to i fix this. or any alternative for connect-mongo.

And sorry for too many questions.
