db seed with mysql database : Cannot read property 'concat' of undefined

[fiftoine]

• Platform: Windows 10 64-bit
• Database: Mysql
• Lux Version: 1.2.2
• Node Version: 8.9.3

Considering the following situation:

lux new testApp --database mysql lux g resource user email:string password:string

Updated seed.js :

import User from 'app/models/user';

export default async function seed(trx) {
  await User.transacting(trx).create({
    email:'[email protected]',
    password: "password"
  })
}

Created test_app_dev mysql database

Called : lux db:migrate

When calling

lux db:seed

I got the following error message :
