Describe the bug

When using Jsonnet to generate manifests, std.parseYaml function returns incorrect result when string values contain ---

I've also filed an issue here:

google/jsonnet#1147

Jsonnet go implementation (https://github.com/google/go-jsonnet) seems unaffected when I tested it locally (which is strange, because I believe that's the version argocd is using).

To Reproduce

Create an app with test.jsonnet file with the following content:

{
  apiVersion: 'v1',
  kind: 'ConfigMap',
  metadata: { name: 'repro' },
  data: {
    'key': std.parseYaml('a: bad---'),
  },
}

Expected behavior

the key value should be {"a": "bad---"} and not [{"a": "bad---"}]

Apologies, after receiving some feedback on issue google/jsonnet#1147 I've realised that I've got it wrong way around - it's the go-jsonnet version that affected (which explains why argocd is affected too). Also, opened the issue in relevant project now - google/go-jsonnet#749
