error messages

[HughP]

When using {{< bibliography >}} and the bib.json file can not be found the site render fails. But there is no output to the terminal saying where or why the problem exists. errorf using https://gohugo.io/functions/errorf/ might save some users down the road.
Currently I get the following error. A more helpful error might include which leaf-bundle was trying to be processed and that hugo-cite couldn't find a bibliography JSON file.
