BeforeUpdate Hook with bulkUpdate

Hi guys,

I’m trying to perform a hook to retrieve information about my item’s reference.

 export function BaseFonctions_beforeUpdate(item, context) {
     wixData.query("BaseContacts").eq('_id', item._id_contact._id).limit(1).find()
        .then((results) => {
        item.title = results.items[0].ent_contactPrenom + ' (' + item.fonction.replace(/,/gi, ".") + ')';
        })
}

It works well using update() function, but when I use bulkUpdate, all my reference are updated with a unique reference field, which by the way isn’t part of my bulkUpdate request.

Any idea ?

Thanks in advance for your help
