Error 'Unknown column type "tinyint" requested' while upgrading PrestaShop

Module version

1.8.2

PrestaShop version

1.7.8.8

PHP version

7.4

What went wrong?

Updating PrestaShop to version 1.7.8.9 fails due to an error while updating the database schema.

The error says:

Error thrown while running command "prestashop:schema:update-without-foreign --env=prod". Message: "Unknown column type "tinyint" requested. Any Doctrine type that you use has to be registered with \Doctrine\DBAL\Types\Type::addType().

This is because the Doctrine entity definition contains an invalid column type in /src/Entity/MyparcelOrderLabel.php:

/**
     * @var int
     *
     * @ORM\Column(name="is_return", type="tinyint")
     */
    private $isReturn;

The correct type here would be "boolean", which is mapped to a TINYINT with a length of 1 (in a MySql database).

Reproduction steps

Use the PrestaShop 1-Click upgrade module to upgrade PrestaShop and to reproduce the error, or trigger the schema update manually using the console: bin/console prestashop:schema:update-without-foreign --env=prod
