Hello Harsha,

You can use listCollections method to get collections, before that you need to update the below line because I have done it directly with a model in my script,

const firstUseDB = firstConn.useDb(firstDB.db);

Now check is connection open then get the list of collections,

firstConn.on('open', () => {
  firstUseDB.db.listCollections().toArray().then((names) => {
    console.log(names)
  })
  .catch((err)=>{
    return err;
  });
});
