How to AutoPopulate inside a object

[suryabigapp]

status: {
      type: {
        id: {
          type: ObjectId,
          ref: 'CustomerStatus',
          autopopulate: { select: 'title' },
        },
        updatedBy: {
          type: ObjectId,
          ref: 'User',
          autopopulate: { select: 'name' },
        },
        updatedAt: {
          type: Date,
        },
      },
    },

Something like this

Remove the type key, because as written, your schema defines status as a Mixed path, and autopopulate doesn't look underneath mixed paths.

status: {
      //type: {
        id: {
          type: ObjectId,
          ref: 'CustomerStatus',
          autopopulate: { select: 'title' },
        },
        updatedBy: {
          type: ObjectId,
          ref: 'User',
          autopopulate: { select: 'name' },
        },
        updatedAt: {
          type: Date,
        },
      },
    },
