Node.js CosmosDB Unknown Collection

What results can you expect?

Some example scenarios are shown below:

Cosmos DB client creation

const CosmosClient = require("@azure/cosmos");
const endpoint = '127.0.0.1:8060'

const client = new CosmosClient({ endpoint: endpoint, auth: { masterKey } });

Database and collection creation

...

const databaseId = 'My database'
const collectionId = 'My collection'

// CREATE DATABASE
const dbResponse = client.databases.createIfNotExists({
  id: databaseId
});
database = dbResponse.database;

// CREATE COLLECTION
const coResponse = database.containers.createIfNotExists({
  id: collectionId
});
container = coResponse.container;

These declarations create a useSelectLink from the source code to the collection

// QUERY
var param = {
    query: "SELECT * FROM root r WHERE r.completed=@completed",
    parameters: [
        {
            name: '@completed',
            value: false
        }
    ]
};

const { result: results } = container.items
    .query(param)
    .toArray();

This declaration create a useDeleteLink from the source code to the database

client.database(databaseId).delete()
