the mongodb database doesn't exist after using lb4 datasource to create a database connection in loopback4

[Barnette-ao]

I have use loopback4 to get an database connection with mongoDB datasource.

I expect after I created the data source,then the datasource will exist in the mongoDB.

this is my datasource file as follows:

const config = {
  name: 'echo3D2',
  connector: 'mongodb',
  url: 'mongodb://localhost:27017/echo3D2',
  host: 'localhost',
  port: 27017,
  user: '',
  password: '',
  database: 'echo3D2',
  useNewUrlParser: true
};

I think that means I have being successful in creating a database in MongoDB,which name is echo3D2.

then when I check whether the database exist or not,I found the echo3D2database does not exist in MongoDB. as the follow show in mongoDB CLI

input:

db.getMongo().getDBNames().indexOf("echo3D2");

output:

-1

there must be something wrong with it !

what should I do to solve the problem ?
