Output is not valid JSON if outputFormat=Json is requested

[jdvor]

CLI outputs invalid JSON when outputFormat=Json is requested. This defeats the whole purpose (further processing) of such output format.

Example:
dotnet-octo push --package="Skeleton.App_alpine-x64.1.1.0.tar.gz" --overwrite-mode=FailIfExists --space="Default" --timeout=300 --outputFormat=Json

Output:

Found space: Default (Spaces-1)
{
  "SuccessfulPackages": [],
  "FailedPackages": [
    {
      "Package": "/home/jan/dev/dotnet-daemon/artifacts/Skeleton.App_alpine-x64.1.1.0.tar.gz",
      "Reason": "There was a problem with your request.\n\n - A package with the same ID and version already exists. To proceed anyway, specify an overwriteMode of OverwriteExisting or IgnoreIfExists.\n"
    }
  ]
}

The stdout output is not valid JSON and could not be piped to tools like jq.
