TYPO3.Fluid

I have an exception just trying to retrieve objects from DB and displaying in a view
$apuntes = $this->apunteRepository->findAll();
$this->view->assign('apuntes',$apuntes);

Attached an export from my DB and MySQL variables

Note: this tables and data were not created by Doctrine. I have imported them from a mysqldump export from other DB.

Uncaught Exception in FLOW3
