Hugo: panic: invalid taxonomy state for ...

[aquilax]

I just upgraded to the latest version of hugo:

$ hugo version
Hugo Static Site Generator v0.55.4-57900417 linux/amd64 BuildDate: 2019-04-25T07:38:50Z

And this is the error which I am getting while running the build:

$ hugo

panic: invalid taxonomy state for "/tmp/site/content/predavane/_index.md" with sections [predavane]

_index.md contains only:

{
   "title": "Predavane" 
}

and in config.toml i have

[taxonomies]
  predavane = "Predavane"

[bep]

I'm not sure exactly why it fails for you (it should not have panicked, and I'll fix that), but I do suspect that this is a section and not a taxonomy.

Try to remove the taxonomy config (if I misunderstand this and this really is a taxonomy, try to make it lowercase: "Prevadane" => "prevadane")

[aquilax]

Can confirm that removing the [taxonomies] section from the config worked.
Thank you for the quick reply.

@bep I get a similar panic if I make an _index.md file, containing a title, for a taxonomy term that's not used in any posts.

In my case, a tag is only used in some future-dated or draft posts. I can build the site if I enable drafts, otherwise hugo panics.
