Thanks for the report! Is there a way that I can reproduce this error? Is the code open source?

[Langellotti]

I managed to solve the problem, which was caused by using the 'package_info_plus' library in my test directory, leading to an error. I removed this library, and the documentation generation works now! Thank you!

[srawlins]

Curious! Glad you sorted it out.
