Panic when building on Netlify

support

Hi,

On MacOS, I upgraded Dart Sass and it works fine. However, at Netlify I have constant reproducible same issue:

8:03:38 PM: Start building sites …

I have not seen this in the Dart Sass projects I have tested on, but the stack trace should be enough to fix it. Thanks. See

OK, I’m pretty sure I know why you get a nilpointer, but that masks another issue: That you don’t have a working Dart Sass version installed. I think you should have some kind of WARNING about this in the log.

Most likely this comes from an old dart-sass-embedded version.

I found how to install separately Netlify Dart Sass Plugin, but at first try it was failing, I didn’t finish my attempts yet: @gethinode/netlify-plugin-dartsass - npm

Wow and at bottom of this page (I just noticed) link to official Hugo documentation, I’ll try it today:

I followed instructions found at ToCSS | Hugo and it works.

Snippet from netlify.toml:

[build]
publish = "public"
command = """\
  curl -LJO https://github.com/sass/dart-sass/releases/download/${DART_SASS_VERSION}/dart-sass-${DART_SASS_VERSION}-linux-x64.tar.gz && \
  tar -xf dart-sass-${DART_SASS_VERSION}-linux-x64.tar.gz && \
  rm dart-sass-${DART_SASS_VERSION}-linux-x64.tar.gz && \
  export PATH=/opt/build/repo/dart-sass:$PATH && \
  npm ci && \
  hugo --gc -b $URL \
  """

[build.environment]
NODE_VERSION = "23.1.0"
HUGO_VERSION = "0.139.0"
HUGO_ENABLEGITINFO = "true"
HUGO_ENV = "production"
GO_VERSION = "1.23.2"
DART_SASS_VERSION = "1.81.0"
TZ = "America/Toronto"

Thank you!
