"__h_pp_l1_144_RelPermalink__e=" Error Message

Hi all,

Everytime I run my hugo server for development, some pages are not loaded properly, causing the CSS is not loaded (the UI become ugly).

When I debug from the browser console, it shows error like below:

GET http://localhost:1313/notes/2025/07/some-post-title-name/__h_pp_l1_144_RelPermalink__e= net::ERR_ABORTED 404 (Not Found)

When I checked the error location in the code, it’s actually related to my CSS loading syntax is not using actual name, causing the page style is becoming ugly (because the CSS is not loaded).

<link 
  rel="stylesheet" 
  href="__h_pp_l1_144_RelPermalink__e="
  integrity="__h_pp_l1_144_Data.Integrity__e=" 
  type="text/css" 
/>

And below are my hugo pipeline syntax to load the CSS:

<!-- Hugo Pipes for CSS -->
{{- $css := resources.Get "css/style.css" -}}
{{- if $css -}}
  {{- if hugo.IsServer -}}
    {{- $css = $css | resources.ExecuteAsTemplate (printf "css/styles.dev.%v.css" now.UnixMilli) . -}}
  {{- end -}}
  {{- $css = $css | resources.Minify | resources.Fingerprint | resources.PostProcess -}}
  <link
    rel="stylesheet"
    href="{{ $css.RelPermalink }}"
    integrity="{{ $css.Data.Integrity }}"
    type="text/css"
  />
{{- end -}}

And this is how I run my hugo dev server:

hugo server --environment=development --buildDrafts --watch --ignoreCache --noHTTPCache --navigateToChanged --poll 1s --logLevel 'debug' --port 1313 --forceSyncStatic --templateMetrics --templateMetricsHints

Does anyone had experience the same problem in the past?

I’m using Hugo version v0.148.1

please help. Thanks in advance!

Hi @sidoki,

regarding your issue

  • I would say that’s why the docs on resources.PostProcess tell us:

    Limitations

    Do not use resources.PostProcess when running Hugo’s built-in development server.
    The examples above specifically prevent this by verifying that the current environment is not “development”.

some reading:

and please let me mention one thing:

  • This is the community support forum, so there’s no need to use name calling with a new topic.

Thanks @irkode for the help. Also, well noted for your advice. :saluting_face:

Name tags is the correct way to frame it (I think). Name calling has a negative meaning (the use of abusive names to belittle or humiliate another person).
