Fontist is possibly causing automated builds on GitHub Actions to crash

[ghobona]

Fontist appears to be causing automated builds on GitHub Actions to crash.

An example Actions log is https://github.com/opengeospatial/ogcna-auto-review/actions/runs/8521643842/job/23340220916

The Action script is https://github.com/opengeospatial/ogcna-auto-review/blob/main/.github/workflows/generate_20-058.yml

The following error message is reported each time the crash occurs:

/usr/local/bundle/gems/fontist-1.20.0/lib/fontist/font.rb:220:in `request_formula_installation': undefined method `each' for nil:NilClass (NoMethodError)

      paths.each do |path|

    from /usr/local/bundle/gems/fontist-1.20.0/lib/fontist/font.rb:206:in `each'

and also this error message:

This particular build should work now (the Space Mono font is fixed) but the issue persists in general since Google Fonts changed its API significantly. I'm working on it here.

I can confirm that the automated builds are now completing without the fontist issue.

Thanks @alexeymorozov and @ronaldtse for the fix.

@ronaldtse This Issue may now be closed.
