Error: No such host is known

[FSou1]

When I use the following host:

const connector = new MongoDBConnector({
  uri:
    "mongodb://admin:RehlmKTm5pr9f9MG@cluster0.vsk29.mongodb.net/test?retryWrites=true&w=majority",
  database: "test",
});

I get the following error:

error: Uncaught (in promise) Error: No such host is known. (os error 11001)
    at processResponse (deno:core/core.js:223:11)
    at Object.jsonOpAsync (deno:core/core.js:240:12)
    at async Object.connect (deno:runtime/rt/30_net.js:224:13)
    at async MongoClient.connect (client.ts:20:18)

    at async Database.query (database.ts:227:21)
    at async Function.createTable (model.ts:161:5)
    at async Database.sync (database.ts:197:7)

The same host is normally connected with Node.js and the mongodb npm package.

Hi Maxim,

This might be an error coming from deno_mongo which is the driver used in denodb for Mongo.

Could you see if connecting to your URI from their documentation example works for you?

If it does, then it might be a case of upgrading this driver version which I can help with.
Otherwise, this should be dealt with on their repository instead.

Let me know so we can figure this out together!

Hi Arnaud,

No, it does not work (I've also created an issue in their repository).

I managed to connect to my local instance with mongodb://localhost:27017. However, the initial URL (mongodb+srv://) is used to connect to the MongoDB Cloud instance, which isn't something unusual and probably has to be supported.

[eveningkid]

Mmm, I believe most people are using their cloud service so you're right it should be supported.

For now, I will close this issue since this isn't directly related to denodb and will eventually be fixed with the driver.

If there is anything else, let me know :)

[FSou1]

Yes, you are right.

This fix should be applied to the driver side once the Deno resolveDns API becomes available.
