Data type not changing in mongo DB after I made changes to mongoose schema

Question

I recently made changes to my mongoose schema from String to Number. When I read data from db, it show as Number but when I try making filters based on the changed property, I don't get any document that was saved before the schema changes were made. When I check using Robo 3T, I see the data types are still showing string. I wish to change all to Number. The data type doesn't seem to change even after I make updates to the document.

const mySchema = new mongoose.Schema(

 {
    status: {
      type: Number,
      default: 1
    }
}...)

Here is how it looks like in the DB

I'll appreciate any help

Answer 1

I switched from using findOne

mySchema.statics.updateStatus = async function(id, status){
  try{
    const record = await this.findOne({_id: id});
    if(record){
      record.status = parseInt(status);
    }
    const updatedRecord = await record.save();
    return updatedRecord;
  }catch(err){
    return null;
  }
}

To using fineOneAndUpdate

mySchema.statics.updateStatus = async function(id, status){
  try{
    const record = await this.findOneAndUpdate({ _id:id }, {status}, {
      returnOriginal: false
    });
  
    return record;
  }catch(err){
    return null;
  }
}

And it updated the data type in the DB.
