E11000 duplicate key error index in mongodb mongoose

Question

Following is my user schema in user.js model -

var userSchema = new mongoose.Schema({
    local: {
        name: { type: String },
         


        

Answer 1

This is because there is already a collection with the same name with configuration..Just remove the collection from your mongodb through mongo shell and try again.

db.collectionName.remove()

now run your application it should work
