v5.14.1 throws errors if pattern Twig file isn't in a subfolder

[coreylafferty]

I am using Pattern Lab Node v5.14.1 on Linux, with Node v12.19.0, using a edition-twig Edition with the starterkit-twig-demo starter kit.

Expected Behavior

Patterns can live in subfolders (e.g, _patterns/pages/article/article.twig) and root folders (e.g., _patterns/pages/article.twig) without errors.

Actual Behavior

If a Twig pattern file is in one of the root folders (e.g., most of the files in the templates and pages folders in the starterkit-twig-demo starterkit), errors like the following are shown during compile. These errors do not seem to negatively affect the output files.

There was an error setting pattern subgroup data after markdown parsing for source/_patterns/pages/_.md
Error: ENOTDIR: not a directory, open '/app/source/_patterns/pages/article.twig/_.md'
There was an error setting pattern subgroup data after markdown parsing for source/_patterns/pages/_.md

Steps to Reproduce

Install the latest version of PL (5.14.1) with the Twig engine and starterkit-twig-demo starterkit and compile the files using the normal commands (e.g., npm run build).

@coreylafferty, can you show me which dependencies you have in your package.json?

What I tried to reproduce.

npm create pattern-lab
// use PHP twig starter

npm run build

Did I do something wrong?

[JosefBredereck]

And can you provide a screenshot of the file structure of your pages folder?

[coreylafferty]

Yes, that's right. Just install and run it with the PHP/Twig options. Not changing any files.

$ npm create pattern-lab
// use PHP twig starter
$ npm run build

I had someone else run the same test under some different conditions to confirm it's not something about my system. Here's the details of their setup and the output they saw (their version of Node is a bit old, but I saw the same thing on a newer version).

Note that the build does seem to finish and things appear to work fine... the issue is just the error messages it throws during the build. It looks like non-nested Twig/MD files in the root folders (e.g. pages or templates) are triggering it to look for a non-existent MD files (like /patterns/pages/.md)
