Bug Report

• Where did you experience the problem? E.g. Azure Web Apps, Azure Functions, Azure Container Registry, or offline use.

Azure Web Apps

• If your repo is publicly available please share its URL:

https://github.com/dagholmus/test-doks (brand new clone of the theme, with the same deploy error)

• What happened?

I'm having some issues deploying a Hugo site, with the theme Doks to Static Web Apps. The theme contains npm modules, with package.json.

Build/deploy works both locally and to Netlify, but not to Azure Static Web Apps.

Error message:

POSTCSS: failed to transform "main.css" ... A system error occurred: uv_os_homedir returned ENOENT (no such file or directory)

I have tried the following:

• Add CUSTOM_BUILD_COMMAND / PRE_BUILD_COMMAND in environemnt to install postcss-cli (and postcss, @fullhuman/postcss-purgecss, autoprefixer)
• Set HOME and HOMEPATH in environment
• Added the npm install postcss-cli command (tested both local and global) in the GitHub workflow file (.yml)
• Tested different versions of Node and Hugo
• Specifying Hugo version in workflow config
• Tested to use npm run build instead of the default Hugo

• What did you expect or want to happen?

To build and deploy the site.

• How can we reproduce it?

Build and deploy Hugo with the Doks theme to Azure Static Web Apps.
