Add Code postal to listing retailer

[sr-expert]

Bonjour

j'ai ajouté dans la collection
$this->getSelect()->joinLeft(
['secondTable' => "smile_retailer_address"],
'e.entity_id = secondTable.retailer_id'
);

quand je filter par psotcode

{
"error": "The "postcode" attribute name is invalid. Reset the name and try again.",
"errorcode": "0"
}
