const Sequelize = require("sequelize")
const db = require("../db")

// model
module.exports = db.defineModel("comments", {
  pid: Sequelize.STRING(50),
  title: Sequelize.STRING(50),
  content: Sequelize.STRING(255),
  username: Sequelize.STRING(50),
  userid: Sequelize.STRING(50),
  avatar: {
    type: Sequelize.STRING(100),
    allowNull: true
  },
  replyArr: {
    type: Sequelize.JSON  // JSON .  PostgreSQL, SQLite and MySQL.
  }
})

the error in the console is as follows:

it seems that only Sequelize.JSON can support mysql, but try or report an error

I hope the bosses will give us some advice!
