Got a template error when following the Getting Started instructions

[billux]

Tested using the latest version of hugo (extended version) running in docker:

$ hugo version
hugo v0.111.3-5d4eb5154e1fed125ca8e9b5a0315c4180dab192+extended linux/amd64 BuildDate=2023-03-12T11:40:50Z VendorInfo=hugoguru

Steps to reproduce: just follow the Getting Started instructions:

$ hugo new site my-site --format=yaml
$ cd my-site/
$ hugo mod init github.com/username/my-site
$ hugo mod get github.com/imfing/hextra
$ cat <<EOT >>config.yaml
module:
  imports:
    - path: github.com/imfing/hextra
EOT
$ hugo new content/_index.md
$ hugo new content/docs/_index.md
$ hugo server --buildDrafts --disableFastRender

The hugo server throws:

Start building sites … 
hugo v0.111.3-5d4eb5154e1fed125ca8e9b5a0315c4180dab192+extended linux/amd64 BuildDate=2023-03-12T11:40:50Z VendorInfo=hugoguru

I'll look into that. In the meantime can you try using the template repository instead?

Ok so using the template repository works.

First, I realize that the latest docker image for hugo doesn't match the latest hugo version (open issue here).

The hugo version used in the Github Action of your template is the 0.117.0 (not the latest one, but still more recent than the latest hugo docker image, which is 0.111.3).

If I try to clone the repo created from the template and run the build locally (with hugo 0.111.3 in docker), hugo serve throws new errors:

$ hugo serve

I get the same errors if I set hugo version to 0.111.3 in the .github/workflows/pages.yaml, so I guess it is due to hugo's version. The weird thing is that it's not the same error about LanguageCode from my first post.

[imfing]

Yeah the languageCode was introduced in v0.112.0
