escaping comma for faker on lumen seeder - php

Question

I'm learning to do some simple migration and seeding on lumen using factory and faker to mysql database, below are my codes :
PostSeeder.php
use Illuminate\Database\Seeder;
class PostSeeder extends Seeder
{
public function run()
{
factory(App\Models\Post::class, 40)->create();
}
}
and on the factory PostFactory.php
$factory->define(Post::class, function (Faker $faker) {
return [
'post_id' => Str::uuid(),
'title' => $faker->sentence(3),
'content' => $faker->realText(200),
'user_id' => Str::uuid(),
'created_at' => $faker->dateTimeBetween('-1 years', 'now')->format('Y-m-d H:i:s'),
'created_by' => Str::uuid(),
'app' => NULL
];
});
when I tried to run the seeder got error like this :
SQLSTATE[22001]: String data, right truncated: 1406 Data too long for
column 'user_id' at row 1 (SQL: insert into 'posts' ('post_id', 'title',
'content', 'user_id', 'created_at', 'created_by', 'app') values

ipsa corrupti., King triumphantly, pointing to the shore, and then
treading on her spectacles, and began picking them up again as quickly
as she could. The next thing was snorting like a wild beast,

I'm not sure, but looks like on faker realText comma is not being escaped on the query, is there anything I need to add on the factory to escape the faker, or need to do something on the database?
I'm using mysql 14.14 on ubuntu 18.04 and lumen 7.x
on posts table the content type is text
