Hiera / HI-231
Hiera's recursion breaks if a backend returns nil
We have hiera using the result of a hiera call as a data source, like this: pre :backends: - site - yaml :hierarchy: - %{hiera('site')} - defaults /pre The site backend can return either nil (no data found), or a string representing the site code (i.e LAB), so that we can then have a specific YAML file per site. This all works ...

We have hiera using the result of a hiera call as a data source, like this:
pre :backends:
site
yaml :hierarchy:
% {hiera('site')}
defaults /pre
The site backend can return either nil (no data found), or a string representing the site code (i.e LAB), so that we can then have a specific YAML file per site.
This all works well, unless the site backend returns nil, in which case hiera gets itself stuck in a loop until it fails with a SystemStackError.
A snippet of the Hiera output is below. For ease of reproduction, site_backend always returns nil. pre
