[Google Sheets] Creation d'un PDF a partir d'un onglet google Sheet

Bonjour,

J'ai plusieurs onglets sur un fichier google sheets et j'aimerai choisir un onglet, le convertir en PDF et l'envoyer ensuite par email.

Mon probleme est au niveau du token et de la fonction URrLFetchApp.fetch
Je recois une erreur du type

Citation:

Request failed forhttps://docs.google.com returned code 401. Truncated server response: <HTML> <HEAD>

D'apres mes recherche, il s'agirait d'une histoire de token et de long-lived refresh token, mais je ne comprend pas comment corriger cela.

Merci par avance pour votre aide !
