            require: true,
            type: [
              {
                isReady: {
                  type: Boolean,
                  default: true,
                },
                creatorId: {
                  type: String,
                  required: true,
                  trim: true,
                },
                creator: {
                  type: String,
                  required: true,
                  trim: true,
                },
                body: {
                  type: String,
                  required: true,
                  trim: true,
                  min: [3, "Must be at least 6, got {VALUE}"],
                },
                timestamp: Number,
              },
            ],
          },

i tried this but still not getting any error if the body is empty or the creator

await PostModel.findOneAndUpdate(query, update, options, (err, doc) => {
      // if (!err) return res.status(201).send(doc);

      return res.status(400).send(err);
    });
