    I’m going to guess that your local XAMPP development server is running MySQL 8.0.13 or newer — or MariaDB 10.2.1 or newer. Prior to that version, MYSQL did not allow a DEFAULT value other than NULL for JSON columns. In MariaDB, JSON is an alias for LONGTEXT, which likewise (starting with version 10.2.1) allows DEFAULT values.

    Probably your development environment allows the defaults and the production environment doesn’t. You can either upgrade your production system or not use that feature.

    Remove the default value:

    ALTER TABLE users ADD COLUMN house LONGTEXT NOT NULL;
