Peso e valore di spedizione Fedex non vengono impostati durante la creazione dell'ordine a livello di codice

Sto provando a creare un ordine a livello di codice usando il metodo di spedizione FedEx. Altri metodi stanno funzionando bene. Quando sto impostando FedEx ottenendo l'errore come per favore specifica il metodo di spedizione. Dopo il debug vengo a sapere che peso e valore sono pari a zero ma ho menzionato il peso e il valore del prodotto.

Codice :

Aiutatemi su questo ho provato forfettariamente e la spedizione gratuita funziona ma FedEx non funziona.

Vai al catalogo, seleziona il prodotto e aggiungi peso nel campo dell'attributo peso.
