Symfony version	4.0.0-BETA2

Using Symfony Flex with version 4.0.0-BETA2 with the composer.json below, when logging in or as anonymous and trying to access the doctrine section or security section of the web profiler returns the following error for both (all other sections are fine)

Type error: Argument 2 passed to Symfony\Bundle\WebProfilerBundle\Twig\WebProfilerExtension::dumpData() must be an instance of Symfony\Component\VarDumper\Cloner\Data, null given, called in /beta2/var/cache/dev/twig/01/0179a685ace86281d0a70ef66f92ed078b595a533f89935addc2d2832b7b3795.php on line 749

I have the same issue. Can't use profiler.

[xabbuh]

Can one of you create a small example project that allows to reproduce your issue?

[millnut]

@xabbuh Yep I should be able to create one later this evening once out of work

[millnut]

@xabbuh had some free time testcase is here https://github.com/limitstudios/beta2test

Security webprofiler error is very touch and go whether it happens

The doctrine webprofiler error happens logged in or out; or any section with database interaction; I have also added the test login in the README

[xabbuh]

Thanks for providing the example. However, this does work for me. The only thing I changed locally was to use SQLite instead of MySQL. Can you debug what is tried to be dumped when you get this error?

[millnut]

@xabbuh Yep I used MySQL I will get the exact version tomorrow. How would I go about getting the dump contents would the contents of the stack trace be enough? It’s quite large so do you want as a text or attached as a file?

[xabbuh]

You could create a gist and link to it here.

If you want to debug this yourself, I suggest to configure Xdebug and add a breakpoint that would allow you to inspect what is going on.

[ad3n]

Yes... I have same issue

[gogus]

I have the same issue.

[ogizanagi]

Could any of you try to identify which of the profiler_dump calls cause this in both https://github.com/symfony/symfony/blob/master/src/Symfony/Bundle/SecurityBundle/Resources/views/Collector/security.html.twig and https://github.com/doctrine/DoctrineBundle/blob/master/Resources/views/Collector/db.html.twig#L241 and what is the data we're actually trying to dump?

Might be the same issue as in #23050

[ogizanagi]

Could you try #24829 please?
Regarding the doctrine panel, an issue should probably be opened in the DoctrineBundle repository.

[gogus]

Created: doctrine/DoctrineBundle#730

[ogizanagi]

Thanks @gogus! Does #24829 solve the issue regarding the security panel?

[gogus]

For me the security panel was ok. I had only problem with doctrine.

[xabbuh]

@limitstudios @ad3n Can you check if #24829 fixes your issue?

[millnut]

@ogizanagi @xabbuh #24829 does fix the security panel error, I will keep an eye on doctrine/DoctrineBundle#730 for any further testing needed

[derrabus]

Regarding the Doctrine panel, the exception is caused by the inclusion of WebProfilerBundle's table template:

https://github.com/doctrine/DoctrineBundle/blob/41d6b7c9a1a37e08ab1c321193446c12d6afb5ed/Resources/views/Collector/db.html.twig#L283

https://github.com/doctrine/DoctrineBundle/blob/41d6b7c9a1a37e08ab1c321193446c12d6afb5ed/Resources/views/Collector/db.html.twig#L293

As a side effect of #23056, the table cannot be used anymore on arrays of strings.
