Getting this error when building pages from a data source with current Hugo version `0.123.0`

```auto
Error: error building site: render: failed to render pages: render of "home" failed: "C:\hugo-site\remote\data\layouts\index.html:3:25": execute of template failed: template: index.html:3:25: executing "index.html" at <transform.Unmarshal>: error calling Unmarshal: unknown format

```

```auto
{{- $URL := "<!-- remote JSON file -->" }}
{{ with resources.GetRemote $URL }}
{{ $data := . | transform.Unmarshal }}
{{ range $data.features }}
{{- with .properties }}
{{/* 1. */}} {{ $string := jsonify . }} 
{{/* 2. */}} {{ $filename := printf "data/%s.md" (urlize .Data_Name }} 
 {{/* 3. */}} {{ $resource := resources.FromString $filename $string}}
