Symfony2 | Error: Invalid serialization data for datetime object

Question

I've been seeing this error in my logs for a couple of days ago when I did a composer update of my project.  

[2015-09-28 17:51:21] php.CRITICAL: Fatal Error: Invalid serialization data for DateTime object

Is it a bug Symfony2?

Answer 1

First of all, you should provide more information, if you want someone help you. But for now, I can suggest you to look at this issue posted on bugs.php.net.

Here is the solution posted there:

public function serialize() {
    return \serialize(array($this->myDateTimeObj->format('Y-m-d H:i:s')));
}
