Verified the new URL with PostMan:

curl --location 'https://facade-maint-config-windows-use-ssh-6f3kfepqcq-ew.a.run.app/v1/provision' \
--header 'Content-Type: application/json' \
--data '{
    "url": "https://api.github.com/repos/puppetlabs/puppetlabs-sqlserver/actions/runs/15700030985",
    "VMs": [
        {
            "cloud": null,
            "region": null,
            "zone": null,
            "images": [
                "windows-2022"
            ]
        }
    ]
}'

Hi @span786. Instead can you please set the SERVICE_URL. See here which shows that if this environment variable is not set then the code selects the default_uri. This provision_service doc explains a bit about this and here's an motd example for changing the service url.

Closing this out for now, but please feel free to reach out!
