PrismaClientUnknownRequestError in prisma.user.create(...) with trigger

Bug description

When I try to create a new user I got this error:

prisma:info Starting a mysql pool with 9 connections.
prisma:query BEGIN
prisma:query INSERT INTO `iosef_db`.`user` (`id`,`hash`,`salt`,`password`,`email`,`token`,`tokenExpiration`) VALUES (?,?,?,?,?,?,?)

How to reproduce

await prisma.user.create({
    data: {
        email: '[e-mail]',
        password: 'password',
        tokenExpiration: `1643896265257`,
        token: 'eyJhbGciOiJIUz…Nn0.ouT9RiI6X0vXEkjf9rxfUhIu_UUYZ-ZkRUCuqW-9tUk',
        salt: '$2b$10$q.y4.vrHKxDYMQkeWm9xW.',
        hash: '$2b$10$Qju63Il/erAV1epJyeEk6epdX5/zD.6kC4oTTjTtlHeUpCUDfpHay'
    }
});

Expected behavior

It should create the user without error

Prisma information

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "mysql"
  url      = env("MYSQL_URL")
}

model user {
  id              String @id @default("") @db.VarChar(36)
  hash            String @db.VarChar(80)
  salt            String @db.VarChar(80)
  password        String @db.VarChar(22)
  email           String @db.VarChar(50)
  token           String @db.VarChar(280)
  tokenExpiration String @db.VarChar(50)
}

Environment & setup

• OS: Linux (Inside a docker container node:16.13.0)
• Database: MySQL
• Node.js version: 16.13.0

Prisma Version

3.5.0

Edit

I tried using prisma.user.createMany(...); and it works perfectly!

Ok, now I can reproduce this with 4.3.1.

What happens here is that we generate that empty string default value in the core, and we expect to find this new record with that value. The database generates a UUID, and our SELECT does not find anything.

It is unclear can you even do this with MySQL and an ORM. MySQL does not have RETURNING for an INSERT, so we have no idea what is the generated UUID value for the record.

Easy reproduction with the migration:

-- CreateTable
CREATE TABLE `user` (
    `id` VARCHAR(36) NOT NULL DEFAULT '',
    `hash` VARCHAR(80) NOT NULL,
    `salt` VARCHAR(80) NOT NULL,
    `password` VARCHAR(22) NOT NULL,
    `email` VARCHAR(50) NOT NULL,
    `token` VARCHAR(280) NOT NULL,
    `tokenExpiration` VARCHAR(50) NOT NULL,

    PRIMARY KEY (`id`)
) DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

CREATE TRIGGER insert_guid 
BEFORE INSERT ON `user`
FOR EACH  ROW 
BEGIN 
    SET NEW.id = UUID(); 
END;
