YAML parsing regression?

[shane-davidson]

Is there an existing issue for this?

Current Behavior

We install rancher to downstream clusters via Fleet. This was previously working fine. (on version 2.13.x)

When upgrading to 2.14.1 we now get the error:

error merging manifests: parsing rancher/templates/post-delete-hook-config-map.yaml: MalformedYAMLError: yaml: line 106: could not find expected ':']; WaitApplied(1) [Cluster rancher-production/rancher-comp]; deployment.apps cattle-system/rancher modified {"spec":{"replicas":3}}

Also installing rancher 2.14.1 chart to the downstream cluster. I check the rancher chart for changes to the related files (there are none) which leads me to believe this behaviour is related to fleet changes

Our fleet file looks like this:

---
defaultNamespace: cattle-system
helm:
  repo: "https://releases.rancher.com/server-charts/stable"
  chart: rancher
  version: 2.14.1
  releaseName: rancher
  values:
     we only set the ingress/hostname/bootstrap password

Expected Behavior

I would expect the YAML parsing to still work given the chart did not change those files.
