Hi everybody,

I need some help.
I can't connect to Atlas mongoDB and I don't understand why.

this is the error that I get:

error: A hook (orm) failed to load!
error: Could not tear down the ORM hook. Error details: Error: Consistency violation: Attempting to tear down a datastore (mongodb) which is not currently registered with this adapter. This is usually due to a race condition in userland code (e.g. attempting to tear down the same ORM instance more than once), or it could be due to a bug in this adapter. (If you get stumped, reach out at http://sailsjs.com/support.)

error: Failed to lift app: Error: Consistency violation: Unexpected error creating db connection

Here's my datastore.js file:

/**

 * data when you execute built-in model methods like `.find()` and `.create()`.

@AliHammami Thanks for posting! We'll take a look as soon as possible.

In the mean time, there are a few ways you can help speed things along:

• look for a workaround. _(Even if it's just temporary, sharing your solution can save someone else a lot of time and effort.)_
• tell us why this issue is important to you and your team. What are you trying to accomplish? _(Submissions with a little bit of human context tend to be easier to understand and faster to resolve.)_
• make sure you've provided clear instructions on how to reproduce the bug from a clean install.
• double-check that you've provided all of the requested version and dependency information. _(Some of this info might seem irrelevant at first, like which database adapter you're using, but we ask that you include it anyway. Oftentimes an issue is caused by a confluence of unexpected factors, and it can save everybody a ton of time to know all the details up front.)_
• read the code of conduct.
• if appropriate, ask your business to sponsor your issue. _(Open source is our passion, and our core maintainers volunteer many of their nights and weekends working on Sails. But you only get so many nights and weekends in life, and stuff gets done a lot faster when you can work on it during normal daylight hours.)_
• let us know if you are using a 3rd party plugin; whether that's a database adapter, a non-standard view engine, or any other dependency maintained by someone other than our core team. _(Besides the name of the 3rd party package, it helps to include the exact version you're using. If you're unsure, check out this list of all the core packages we maintain.)_

@AliHammami Thanks for the detailed example code.
Have you tried setting id: { type: 'string', columnName: '_id' }, under attributes?

[AliHammami]

@johnabrams7 i've just tried it, I have the same issues.

[johnabrams7]

@AliHammami It looks like it's having trouble reaching cluster0-kqqjs.mongodb.net - I'm curious if the test?w=majority query string part of the URL is possibly confusing the adapter. Is that required and what happens without it?

[AliHammami]

I don't know if it's required. I deleted it and I have this issue now:

Failed to lift app: Error: Invalid configuration for datastore mongodb: No database could be determined from configuration (tried to use database: undefined).

But if i only delete ?w=majority, I have the same issue:

Failed to lift app: Error: Consistency violation: Unexpected error creating db connection manager:
```
MongoError: failed to connect to server [cluster0-kqqjs.mongodb.net:27017] on first connect [MongoError: getaddrinfo ENOTFOUND cluster0-kqqjs.mongodb.net cluster0-kqqjs.mongodb.net:27017]

[AliHammami]

This is the uri link from atlas mongodb, maybe it can help you to resolve my problem:
mongodb+srv://ali:@cluster0-kqqjs.mongodb.net/test?retryWrites=true&w=majority

I saw in an another post that I have to delete the +srv and retryWhites=true

@AliHammami see this: https://github.com/balderdashy/sails/issues/4590#issuecomment-494669327

@glemiere I've tried it:

adapter: 'sails-mongo',

And I've get this error:

@AliHammami
I found this potential fix on StackOverflow for the same issue with sails-mongo and Atlas mongoDB:

• https://stackoverflow.com/a/43337017/10166674

[AliHammami]

Thank you guys for your help!
I still have the issue :(.

[glemiere]

@AliHammami the error you link is showing that you tried to connect to localhost but your server is at cluster0-kqqjs.mongodb.net.

Try:

adapter: 'sails-mongo',
host: 'cluster0-kqqjs.mongodb.net',
port: 27017,
database: 'YOURDBNAMEHERE',
user:'YOURDBUSERHERE',
password: 'YOURPASSWORDHERE',

Just make sure you have the right information at the right place. Do you know your db name? Are you sure your user has read/write access to it?

[AliHammami]

@glemiere I still have the issue. I know the db name, I have read/write access to it. I tried to connect it with an express.js project and it works fine but I don't understand why it don't want to connect with sails.

[johnabrams7]

@AliHammami - Good to know the credentials are confirmed working. Do you have an example of the working db configuration code from express.js to compare?

[w3villa-mavin]

DID U FIX THIS?

[Lozcep]

I have the same problem. I need help

[YassineMd]

Hey guys I have the same issue and I found the solution on StackOverflow.

Basically you need to update the connection driver version in mongo atlas dashboard from Node.js 3.0 or later driver version to Node.js 2.2.12 or later version.

[eashaw]

Thank you @YassineMd for finding that.

Hope this will help @AliHammami @Lozcep @w3villa-mavin
