Persistent YAML to JSON Conversion Error with KCL Plugin

[oliver-hofmann-cistec-com]

Describe the bug When attempting to generate manifests using the KCL plugin, I encounter the following error: "failed to unmarshal manifest: error converting YAML to JSON: yaml: line 2: mapping values are not allowed in this context." This error persists until I perform a hard refresh, despite making no changes to the codebase.

To Reproduce Steps to reproduce the behavior:

1. Deploy an application using ArgoCD with the KCL plugin.
2. Observe the error in the ArgoCD UI or through CLI output.
3. Note that the error appears consistently until a hard refresh is performed.

Expected behavior Manifest generation should occur without errors, without the need for hard refreshes to correct YAML to JSON conversion issues.

Version

• ArgoCD Version: 6.9.1

Logs generating manifests: failed to unmarshal manifest: error converting YAML to JSON: yaml: line 2: mapping values are not allowed in this context

Additional context The issue occurs consistently under the current setup, using the KCL plugin, and without any recent changes to the YAML files or configurations that might explain this behavior.
