Error fetching FlexSearch

[filcuk]

Hi all,

I've been trying to get this theme running on a quick start hugo site.
The build fails with the following error:

Watching for changes in /src/{archetypes,assets,content,data,i18n,layouts,static,themes}
Watching for config changes in /src/hugo.toml, /src/themes/hextra/hugo.toml
ERROR Could not retrieve FlexSearch js file from https://cdn.jsdelivr.net/npm/[email protected]/dist/flexsearch.bundle.debug.js. Reason: template: _partials/scripts/search.html:12:26: executing "_partials/scripts/search.html" at <resources.GetRemote>: error calling GetRemote: open /cache/src/filecache/getresource/12354019010354757432: no such file or directory.

hugo v0.152.2+extended+withdeploy linux/amd64 BuildDate=unknown VendorInfo=docker
Built in 165 ms
Error: error building site: logged 1 error(s)

I can access the same url just file.
I do see that the problem appears to be with 'no such file or directory', but I don't know how it gets to this path in the first place.

The above is run using docker. I ran hugo from desktop in the same dir and get a different error:

$ hugo server

Any leads would be much appreciated.

I have tried setting environment to production, but except the url returning a non-debug file, the error is the same.

My compose

  hugo-blog:
    container_name: hugo-blog
    image: ghcr.io/gohugoio/hugo:v0.152.2
    restart: "no"
    command: server --bind 0.0.0.0 --source /src
    user: $PUID:$PGID
    volumes:
      - $DOCKERDIR/appdata/hugo/blog:/src:rw

did you try: network_mode: "host"

there was a 'flexsearch.9f5b5908f93ae86f1ecd4b043b799f580c2d1654e703dd9357d568ac41b2547a.js' in 'public/js', but renaming that to 'flexsearch.js' didn't make a difference either
