Comece pela reprodução em museum.py na linha 24, usando Python 3.12.2, Firebase SDK 6.1.0 e a chamada mostrada do cliente Firestore. Verifique se a falha pode ser reproduzida e se é causada pelo SDK ou pela resolução de DNS de firestore.googleapis.com. A conclusão exige identificar um problema reproduzível do SDK e um resultado esperado claro, mas o relatório não define uma alteração de código.

  • Operating System version: Mac OS
  • Firebase SDK version: 6.1.0
  • Firebase Product: firestore
  • Python version: 3.12.2

cred = credentials.Certificate("firebase-privateKey.json")
firebase_admin.initialize_app(cred) 
db = firestore.client()


collections = list(db.collections())
if collections:
    print("Collections found:", [col.id for col in collections])
else:
    print("No collections found or access denied.")

The code fails with error below.

I am running the script once a month, and It was working fine until 2025/1/5.
Suddenly stopped working yesterday (2025/2/1).

I can confirm the reject exists at: https://console.firebase.google.com/u/0/project/art-sanpo/overview?hl=ja
And the Blaze plan is turned on, access rule is allow read: if true; for all of the collections.
