How to transform mongoose schema errors

I would like to transform all mongoose schema errors.

Let's say I've a UserSchema:

const UserSchema = new mongoose.Schema({
  email: {
     type: String,
     unique: true,
     required: [true, 'E-Mail is required']
  },
  password: {
     type: String,
     required: [true, 'Password is required']
  }
}

If I would try to save a user without email and password, I would get following error object back:

{
  "errors": {
    "password": {
      "message": "Password is required",
      "name": "ValidatorError",
      "properties": {
        "type": "required",
        "message": "Password is required",
        "path": "password"
      },
      "kind": "required",
      "path": "password"
    },
    "email": {
     // ...
    }
  },
  "_message": "User validation failed",
  "name": "ValidationError"
}

I would like to transform this error response globally for all my schemas, for example to

{
  errors: [
      { message: "Password is required", path: "password" }
      // ...
  ]
}

Is there a way to apply a transform method globally to all Schema errors? (I would like to avoid to transform each response manually)
