Jmsserializerbundle: Undefined index error

[kbond]

I recently notice that object serialization stopped working in a project. I can't seem to nail down the problem. It seems to work in my test environment but not in dev/prod environment.

I am using the latest master and metadata 1.1.1 and have cleared the cache.

Here is my stack trace:

<error code="500" message="Internal Server Error">
<exception class="ErrorException" message="Notice: Undefined index: product in C:\wamp\www\tardis\vendor\doctrine\lib\Doctrine\ORM\Persisters\BasicEntityPersister.php line 1280">

Closing as not reproducible.

This is because of incorrect schema, run

app/console doctrine:schema:validate
