When running bibtool docs/oscar_references.bib -o docs/oscar_references.bib locally, I get
*** BibTool ERROR: Resource check.error.rule unknown. three times.
Apparently the CI tests do not have this problem.

@ThomasBreuer huh, weird. Which version do you have (run bibtool -h to find out)? The latest is 2.68 from 2020, so I would assume we all use that...

[ThomasBreuer]

Thanks for the hint.
I had bibtool version 2.67. With version 2.68, the messages disappear.
