A weird, ugly Error message when running google_ha_test.py

[Expert@cp-member-a:0]# $FWDIR/scripts/google_ha_test.py
GCP HA TESTER: started
GCP HA TESTER: checking access scopes...

Expecting value: line 1 column 1 (char 0)

Got this message when trying to test a CheckPoint R81.10 cluster build in a new environment. Obviously, this error message is not at all helpful in determining what the problem is. So I wrote a little debug script to try and isolate the issue:

import traceback
import gcp as _gcp 

global api
api = _gcp.GCP('IAM', max_time=20)
metadata = api.metadata()[0]

project = metadata['project']['projectId']
zone = metadata['instance']['zone'].split('/')[-1]
name = metadata['instance']['name']

print("Got metadata: project = {}, zone = {}, name = {}\n".format(project, zone, name))
path = "/projects/{}/zones/{}/instances/{}".format(project, zone, name)

    head, res = api.rest("GET",path,query=None, body=None,aggregate=False)
except Exception as e:

Running the script, I now see an exception when trying to make the initial API call:

[Expert@cp-cluster-member-a:0]# cd $FWDIR/scripts
[Expert@cp-cluster-member-a:0]# python3 ./debug.py

Got metadata: project = myproject, zone = us-central1-b, name = cp-member-a

Traceback (most recent call last):
  File "debug.py", line 18, in <module>
    head, res = api.rest(method,path,query=None,body=None,aggregate=False)
  File "/opt/CPsuite-R81.10/fw1/scripts/gcp.py", line 327, in rest
    max_time=self.max_time, proxy=self.proxy)
  File "/opt/CPsuite-R81.10/fw1/scripts/gcp.py", line 139, in http
    headers['_code']), headers, repr(response))
gcp.HTTPException: Unexpected HTTP code: 403

This at least indicates the connection to the API is OK and it’s some type of permissions issue with the account.

The CheckPoints have always been really tough to troubleshoot in this aspect, so to keep it simple, I deploy them with the default service account for the project. It’s not explicitly called out

I was able to re-enabled Editor permissions for the default service account with this Terraform code:

# Set Project ID via input variable
variable "project_id" {
  description = "GCP Project ID"
  type = string
# Get the default service account info for this project
data "google_compute_default_service_account" "default" {
  project = var.project_id
# Enable editor role for this service account
resource "google_project_iam_member" "default_service_account_editor" {
  project = var.project_id
  member  = "serviceAccount:${data.google_compute_default_service_account.default.email}"
  role    = "roles/editor"
