no path info

Error message

no path info

What it means

A panic in HugoSites.loadData (hugolib/hugo_sites.go:712) when a data file's filesystem metadata has a nil PathInfo (fi.Meta().PathInfo == nil). PathInfo is attached during Hugo's filesystem mounting; nil means the file bypassed the proper path machinery.

Solutions

1. Check module [[mounts]] for the data directory are correct
2. Remove custom filesystem hooks that bypass Hugo's mounting
3. Report a bug with the mount configuration that reproduces it

if fi.Meta().PathInfo == nil {
    return fmt.Errorf("data file %q has no PathInfo; check module mounts", fi.Name())
}

When it happens

Trigger: A file under /data is reached whose Afero metadata lacks PathInfo — e.g., a custom or broken module mount that did not attach path info, or a custom Afero filesystem injected into the data layer.

Common situations: Misconfigured module [[mounts]] for the data dir; a custom filesystem hook bypassing Hugo's mounting; a corrupted Hugo build.
