We are using Kargo v1.10.3 and in our PromotionTask we need to update annotation values in kustomization.yaml. Our annotations use dots in the key names like below:

yaml

commonAnnotations:
  deployment.testing.com/author: shreyank
  build.testing.com/id: abc123
  build.testing.com/branch: main

We are using the yaml-update step but it fails with:

error mutating bytes: error finding key ............ key path not found

We tried all the following key path formats:

yaml

# Attempt 1
- uses: yaml-update
  config:
    path: kustomization.yaml
    key: commonAnnotations.deployment\.testing\.com/author
    value: shreyank

# Attempt 2
- uses: yaml-update
  config:
    path: kustomization.yaml
    key: 'commonAnnotations["deployment.testing.com/author"]'
    value: shreyank

# Attempt 3
- uses: yaml-update
  config:
    path: kustomization.yaml
    key: 'commonAnnotations."deployment.testing.com/author"'
    value: shreyank

All attempts fail with the same key path not found error.

Question: Is there a supported way to use yaml-update with dot-containing annotation keys without changing the existing key format in the file? Or is this a known limitation?
