Make a new migration with

php artisan make:migration change_body_to_nullable_in_reviews_table --table=reviews

where you put this

    public function up()
    {
        Schema::table('reviews', function (Blueprint $table) {
            $table->text('body')->nullable()->change();
        });
    }

    public function down()
    {
        Schema::table('reviews', function (Blueprint $table) {
            $table->text('body')->nullable(false)->change();
        });
    }

And then run PHP artisan migrate
