Problem

With Hugo v0.152.0, I'm getting the following error at running "hugo server".

Error: command error: failed to load modules: invalid module config for "github.com/google/docsy": "../../node_modules/bootstrap": mount source must be a local path for modules/themes

It seems this is happening because that behavior was disallowed by this PR in Hugo.

• hugofs: Make sure that non-project module mounts are local paths gohugoio/hugo#14071
• Disalow ../ mounts in themes gohugoio/hugo#14069

On my end, it started working after I removed the configuration for Docsy as an NPM package from hugo.yaml.
