[kiennd146]

php bin/console -v doctrine:phpcr:fixtures:load
=> Exception
In DoctrinePHPCRODMListener.php line 71:

[Symfony\Component\Debug\Exception\UndefinedMethodException]
Attempted to call an undefined method named "getDocument" of class "Doctrine\ODM\PHPCR\Event\PreUpdateEventArgs".
Did you mean to call "getDocumentChangeSet"?

that looks like you end up with an old version of the sonata-project/cache repository together with a new version of doctrine commons and phpcr-odm. can you try updating sonata-project/cache?
