Can you please share a small reproducing app?

Can you please share a small reproducing app?

Here is a small reproducer.
Steps to reproduce :

• composer install
• symfony server:start
• php bin/console doctrine:migrations:migrate
• Go to http://127.0.0.1:8000/index
• Open DebugBar and see Warnings

I mean an app that I could install myself on my local machine please?

OH I missed the link, let me try it now!

I'm not able to reproduce the issue, I see no warning here :(

Could you try with PHP 7.3?

php -v

PHP 7.3.29-to-be-removed-in-future-macOS (cli) (built: Sep  6 2021 05:14:39) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.29, Copyright (c) 1998-2018 Zend Technologies

Same with this, no issue:
PHP 7.3.31-2+ubuntu20.04.1+deb.sury.org+1 (cli) (built: Oct 22 2021 12:34:45) ( NTS )

That was my only lead that could have explained the difference :/

You might want to debug/dump the value that fails to be serialized and figure out where it comes from...

Already tried but couldn't trace why this can't be serialized :

PhpFilesAdapter.php on line 229:
array:3 [▼
  0 => Doctrine\ORM\Mapping\Column {#468 ▼
    +name: "name"
    +type: "string"
    +length: 50
    +precision: null
    +scale: null
    +unique: false
    +nullable: false
    +options: []
    +columnDefinition: null
  }
  1 => Symfony\Component\Validator\Constraints\NotBlank {#469 ▼
    +message: "This value should not be blank."
    +allowNull: false
    +normalizer: null
    +payload: null
    +groups: array:1 [▶]
  }
  2 => Symfony\Component\Validator\Constraints\Length {#499 ▼
    +maxMessage: "partner.name.max_size"
    +minMessage: "partner.name.min_size"
    +exactMessage: "This value should have exactly {{ limit }} character.|This value should have exactly {{ limit }} characters."
    +charsetMessage: "This value does not match the expected {{ charset }} charset."
    +max: 50
    +min: 2
    +charset: "UTF-8"
    +normalizer: null
    +allowEmptyString: false
    +payload: null
  }
]

It somehow seems like this is related to groups not explicitly defined in @Assert. With the following code, there is no more issues:

/**
* @var string
*
* @ORM\Column(name="name", type="string", length=50)
* 
* @Assert\NotBlank(groups="Default")
* @Assert\Length(groups="Default",
*     min=2,
*     max=50,
*     minMessage="partner.name.min_size",
*     maxMessage="partner.name.max_size"
* )
*/

@nicolas-grekas just to double-check, you don't have any warnings at all?

Because with new Profiler re-design, warning are not displayed on main page:

I have to click on "All messages" to display warnings:

@nicolas-grekas could it be related to aa4fb0c#diff-eadef5e494fbfb85346e70992f4b18994df0b999b7d336c9cece5ab9e9a4a18a unsetting the property ?

Thanks @stof for this lead!
I confirm that there is no more warnings when I comment //unset($this->groups); and re-add $knownOptions['groups'] = true; in Constraint.php on both my reproducer and my app

@nicolas-grekas just to double-check, you don't have any warnings at all?

I confirm I have nothing like that. Anyone else reproducing?

@adrienfr can you please debug the situation a bit more, at least show us the details of the previous ErrorException?

@nicolas-grekas could this be helpful?

I'm available on Slack (Symfony Devs), username adrienfr if you need

I would really need the "previous" exception.

I would really need the "previous" exception.

"User Notice: serialize(): "groups" returned as member variable from __sleep() but does not exist"

Found this related issue but you might remember :) #28352

OK, I now am able to reproduce. I need to run bin/console c:c --no-warmup before refreshing the browser.

Tagging my stack trace #44182 as it seems to be relevant

Thanks for the details.

Thanks @nicolas-grekas
