resources.GetRemote returns nil pointer, but renders temporary file in `with` block, suspect bad MediaType handling?

I would refactor this whole thing.

site config

params:
  cdn:
    jxl:
      decoder:
        remoteURL: 'https://cdn.jsdelivr.net/gh/niutech/jxl.js/jxl_dec.js'
        localURL: js/jxl_dec.js
      loader:
        remoteURL: 'https://cdn.jsdelivr.net/gh/niutech/jxl.js/jxl.min.js'
        localURL: js/jxl.js
      wasm:
        remoteURL: 'https://cdn.jsdelivr.net/gh/niutech/jxl.js/jxl_dec.wasm'
        localURL: wasm/jxl_dec.wasm

template

{{ range site.Params.cdn.jxl }}
  {{ $remoteURL := .remoteURL }}
  {{ $localURL := .localURL }}
  {{ with resources.GetRemote $remoteURL }}
    {{ with .Err }}
      {{ errorf "%s" . }}
    {{ else }}
      {{ with resources.Copy $localURL . }}
        {{ .Publish }}
      {{ end }}
    {{ end }}
  {{ else }}
    {{ errorf "Unable to get remote resource %q" $remoteURL }}
  {{ end }}
{{ end }}
