Error in php artisan migrate laravel

Question

I am using Laravel and I have a transition with a function:

public function up()
{
    Schema::table('articles', function (Blueprint $table) {
        $table->string('article_title',100)->change();
    });
}

and when I do 'php artisan migrate' on my cmd, I get an error:

[Doctrine \ DBAL \ DBALException] An unknown database type name was requested, Doctrine \ DBAL \ Platforms \ MySqlPlatform may not support it.

I don't even use an enumeration! And I also do not have any other migrations that are not portable and have an enumeration.
