Décrivez le problème/l’erreur/la question
En envoyant la commande au site n8n, j’obtiens les erreurs ci-dessous. J’ai vérifié les espaces, les calculs, etc., mais je n’arrive pas à trouver la source de l’erreur. Tous mes nœuds s’exécutent parfaitement lorsqu’ils sont traités individuellement
Quel est le message d’erreur (le cas échéant) ? Votre demande n’est pas valide ou n’a pas pu être traitée par le service. Vos totaux de commande sont incorrects. Veuillez vous assurer que vous calculez les totaux correctement.
