Boolean values not parsed properly to integer fields for MySQL

What are you doing?

isPublic: {type: DataTypes.BOOLEAN, allowNull: false, defaultValue: false}

// ---------
// Later on...

Model.create({key1: 'value1', key2: 'value2'})
//or...
Model.create({key1: 'value1', key2: 'value2', isPublic: true})

What do you expect to happen?

Record being created into the database with a proper converted default value to 0 or 1, since MySQL uses TINYINT(1) as the column type for boolean fields.

What is actually happening?

SequelizeDatabaseError: Incorrect integer value: 'false' for column 'isPublic' at row 1 SequelizeDatabaseError: Incorrect integer value: 'true' for column 'isPublic' at row 1

Dialect: mysql Dialect version: 2.6.0 Database version: 8.0.15 Sequelize version: 5.2.1 Tested with latest release: Yes

Note if this helps anyone. I was still getting that error after upgrading from from 4.42.0 to 5.6.0. It resolved itself after also upgrading mysql2 from 1.4.2 to 1.6.5 and a fresh node modules nuke+install.

This should be resolved in v7 with #14505
