including a , in an unquoted yaml value for a helm chart caused a warn and failure in deployment as incorrect values are presented

[darkedges]

What happened?
Failed to use helm values file and started using incorrect values for deployment into environment.

[warn]   Error reading from chart dev overwrite values E:\development\projects\forgerock\devops\values\environments\devspace\frim.yaml: yaml: line 20: did not find expected key

What did you expect to happen instead?
Expected the devspace to exit with the issue, as this cause the deployment to continue and use incorrect values.

How can we reproduce the bug? (as minimally and precisely as possible)
include a , at the end of an non quoye yaml value

services:
  identity:
    details:
      username: "uid=am-identity-bind-account,ou=admins,ou=identities",

Anything else we need to know?
