Access GAE Service through Service Account

[agnibesh-gr]

I have deployed a GAE Service in flex environment to a VPC.

The ingress setting for the GAE Service is internal-only.

VPC has one firewall rule

• Access all ingress from a specific Service Account

Now, I am trying to access the endpoint of my GAE Service using Service Account Key Json. But I am getting Forbidden Access in response

index.js file (SA Client trying to access GAE Endpoint):

SA Firewall Rule in VPC :
