Ref : https://www.npmjs.com/package/mongoose

// Blog Schema 
{
"description" : { type : string },
"author" : {
    "id" : string
    "username" : string, 
    "type": { type : string } // auther is an object with a type property
 }
}

// Blog find query 
const username = req.params.username  // user name 
Blog.find({"author.username" : username }, (err, data) => {
  if(err) {
    // error handler 
  }else{
    console.log(data)
  }
}

It looks like you have made a typo. You are using account, but in the schema it is author. Try this:

Blog.find({author.username:req.params.username}
