dart-sass-embedded permissions error

[russbiggs]

I'm using this action to attempt to build a site using dart-sass. The build works locally but the action fails with the following error:

hugo v0.107.0-2221b5b30a285d01220a26a82305906ad3291880+extended linux/amd64 BuildDate=2022-11-24T13:59:45Z VendorInfo=docker
Error: Error building site: TOCSS-DART: failed to transform "scss/main.scss" (text/x-scss): got unexpected EOF when executing "dart-sass-embedded". The user running hugo must have read and execute permissions on this program. With execute permissions only, this error is thrown.

This seems pretty straightforward to fix by just adjusting the permissions in the image here:

https://github.com/jakejarvis/hugo-docker/blob/master/Dockerfile#L120

I've attempted this change with

chmod 755 /usr/bin/dart-sass-embedded 

but still get the same error from Hugo. Happy to contribute with a PR, but I'm a bit stuck on what else might be going on here, or if I'm missing something.

I've set up a minimal example repo here:

After more investigation it looks like this may be a much more upstream issue with Dart and Alpine linux support. see more here:
