Subject

When there is a twig error, an error occured when the profiler is retrieving data from blocks.

Steps to reproduce

generate a random twig error, undefined variable for example {{ noExist }}

Expected results

Get information about Sonata blocks from the page in the profiler.

Actual results

http://awesome.app/app_dev.php/_profiler/d6e0ef is in error (500)

Notice: unserialize(): Error at offset 9295 of 70645 bytes

when i comment https://github.com/sonata-project/SonataBlockBundle/blob/3.x/src/Profiler/DataCollector/BlockDataCollector.php#L53

profiler is ok

I guess it's link to php serialization https://wiki.php.net/rfc/custom_object_serialization

Someone has a clue ? tips / tricks ?

Thanks,
Sébastien

Can you provide a PR with a bugfix @cbastienbaron ?

[vsilvestre-accenture]

Same issue here, I have no clue of the actual problem and how to solve it

[franmomu]

I guess it's related with #556

[stale]

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
