Deploying a standard OCP 4.18 cluster (3 masters, 2 workers) with a ZTP profile using siteconfigv2 with hub-side templating
fails to sync gitops policies. The gitops policies app shows the following stack trace:

    Attempting to deploy OCP cluster 4.18.0-0.nightly-2024-11-13-092957
    Hub OCP: 4.17.4
    ZTP site generator: v4.18.0-17
    Gitops: v1.14.0-16

Always
    

    1. Create ZTP siteconfigv2 PGT with hub-side templating
    2. Attempt to deploy node
    3. Observe gitops policies app status
    

Stack trace above, and policy is not rendered.
    

ZTP container should generate a valid policy config.
    

must-gather, etc. will be added in a comment
