Línea de trabajo

Start at /app/main.py line 428 and inspect the types and contents of subsObject and notificationMessageObject passed to pywebpush.webpush. Trace the call through pywebpush/init.py and http_ece/init.py around the reported encrypt failure, then verify that the Flask route can send a push without the unhashable slice error.

Descripción

I have trouble getting pywebpush work for my python backend on gcp.

VAPI PUBLIC KEY and PVT KEY obtained from firebase dash board thourhg manual creation

#subscriptionObject comes from Angular front end. It used the VAPI PUBLIC KEY to receive the object.
I used the package versions specified in requirement.txt.
The call happens from a Flask app route.

webpush(subscription_info = subscriptionObject, data=notificationMessageObject, vapid_private_key=VAPID_PRIVATE_KEY, vapid_claims={"sub": "mailto:[email protected]"})
Error
