API Stripe érronée ?

Default
,

Bonjour,

J'implémente un système de facturation via Stripe sur ma plateforme. Je souhaite ajouter des tax_rate à chacun de mes InvoiceItem en suivant la doc (cf: https://stripe.com/docs/api/invoiceitems/create). Cependant, je n'ai pas l'impression que le package Stripe soit à jour vis-à-vis de la doc. J'utilise Stripe 7.13.19 pour Typescript et il n'y aucun champs tax_rates disponible sur mon InvoiceItem (ou alors je m'en sers mal).

Ce que je fais

Voici comment je crée mon InvoiceItem

newInvoiceItem = await this.stripe.invoiceItems.create({
            customer: billingUser.billingData.customerID,
            currency: this.settings.currency.toLocaleLowerCase(),
            amount: Math.round(transaction.stop.roundedPrice * 100),
            description: description,
            tax_rates: defaultTax
          }, {
            idempotency_key: idemPotencyKey.keyNewInvoiceItem
          });

Ce que je veux

Ajouter des tax_rates à mes InvoiceItem :)
