Cannot resolve attribute 'pid' in the model Metadata file storage

When setting my model metadata to use file with

$di->setShared('modelsMetadata', function () {
    $metadataAdapter = new MetaDataAdapter();
    $metadataAdapter->setStrategy(new \Phalcon\Mvc\Model\MetaData\Strategy\Annotations());
    return $metadataAdapter;
});

I get the error Phalcon \ Mvc \ Model \ Exception: Cannot resolve attribute 'Pid' in the model Anyone have any idea why, what have I done wrong.

My Model
