Cannot invoke Google Cloud Function from GCP Scheduler

Question

I\'ve been trying to invoke a GCP function (--runtime nodejs8 --trigger-http) from GCP scheduler, both located within the same project. I can only make it work,

Answer 1

As per the recent update on GCP, new function needs manual update for authentication.

We need to add Cloud Function Invoker permission to user allusers.

Please refer https://cloud.google.com/functions/docs/securing/managing-access-iam#allowing_unauthenticated_function_invocation
