Hugo error: execute of template failed: template: _default/list.html:8:23: executing 'main' at <.Pages.Date.Reverse>: can't evaluate field Date in type page.Pages

Got this:

Building sites - WARN 2020/02/18 18:08:30 .File.Dir on zero object. Wrap it in if or with: 
{{ with .File }}{{ .Dir }}{{ end }}

Error: Error building site: failed to render pages: render of "section" failed: "C:\matt\website\layouts\_default\list.html:8:23": execute of template failed: template: _default/list.html:8:23: executing "main" at <.Pages.Date.Reverse>: can't evaluate field Date in type page.Pages

I think this was because I had the line:

        {{ range .Pages.Date.Reverse}}

….in my list.html

It should be:

        {{ range .Pages.ByDate.Reverse}}
