J'ai appliqué cette modification dans la db

// issue weight
// 0 issue_no_issue
// 1 issue_missing_product
// 2 issue_wrong_quality
// 4 issue_wrong_product_quality if items.fulfillment.status === fulfilled (after customer feedback) 
db.orders.update(
    {"items.fulfillment.issue": { "$exists": false }, "items.fulfillment.status": "failure"}, 
    {"$set":{"items.$.fulfillment.issue":'issue_missing_product'}}, { multi: true }
  );
