fatal: [localhost]: FAILED! => The task includes an option with an undefined variable #14245

Hi there,

I'm trying to setup a VNP on Scaleway but I got the following fatal error (disclaimer: I'm a newbie 😅):

fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: list object has no element 0\n\nThe error appears to be in '/Users/xx/algo/roles/cloud-scaleway/tasks/main.yml': line 12, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Set cloud specific facts\n ^ here\n"}

Could you please help me set it up the right way? thanks

Cheers, Alexis 😉

Just to confirm, I have the exact same issue with Scaleway. Running algo from Linux. Running the tip of master with a clean config.

Offending file appears to be algo/roles/cloud-scaleway/tasks/main.yml': line 14, column 5.

I did some debugging, and I realized that no organisation data is fetched:

TASK [cloud-scaleway : organization] **********************************************************************************************************************************************
ok: [localhost] => {
    "msg": {
        "changed": false,
        "failed": false,
        "scaleway_organization_info": [],
        "warnings": [
            "https://account.scaleway.com/organizations?"
        ]
    }
}

I found so by inserting the following here:

  - name: organization
    debug:
      msg: "{{ scaleway_org }}"

This points to an issue with this Ansible module.

Looks like the Project ID is needed, not the Organization ID, see https://github.com/trailofbits/algo/discussions/14182#discussioncomment-1852777

I had similar problem with Scaleway. I replaced in /algo/roles/cloud-scaleway/tasks/main.yml line 16 to:

   - name: Set cloud specific facts
     set_fact:
       organization_id: "<my organization id>"

organization I obtained from curl https://account.scaleway.com/tokens/$SCW_ACCESS_KEY -H "X-Auth-Token: $SCW_SECRET_KEY" access and secret key I created in my scaleway account at credentials page. And it works
