node.js - Mongoose: Error using projection when timestamps are enabled

Question

I'm having an issue using projection, particularly the $unset field. I also had the same issue with $pull with arrays. It seems like mongoose uses power-assign under the hood for async for-each operations.

export type IUserModel = Model<IUserDocument>

const UserSchema = new Schema<IUserDocument>({
  email: { type: String },
  meta: {
    created: String,
    updated: String,
  },
  photos: {
    type: Map,
    of: {
      link: String,
      size: Number,
    }
  },
// }, {timestamps: {createdAt: 'meta.created', updatedAt: 'meta.updated' } });
}, { timestamps: true });

export const User = model<IUserDocument, IUserModel>('users', UserSchema);

const removePhoto = async (id, key) => {
  try {
    const query = await User.updateOne({ _id: '' }, { $unset: { [`photos.${key}`]: true } })
    console.log(query)
  } catch(err) {
    console.error(err)
  }
}

I receive the following error:
