Error thrown for every image loaded

[lucor001]

I wanted to see if anyone else is seeing this issue. Images are being loaded correctly, and the module seems to work, but it throws an error into the log file for every image loaded.

Error:

Looking at node_helper.js around line 312 I found that the filesArray[0] is undefined. You can see that above where I added 2 warnings to essentially display imageDirectory and filesArray[0]. Strangely enough everything still seems to work correctly.
Code:

        filesArray = files.filter((file) => file.startsWith(baseFilename) && path.extname(file).toLowerCase() === `${imageFilenameEnumeratedEnd}.json`);
        // actually, there is only one file expected
        Log.warn('imageDir:', imageDirectory);
        Log.warn('firesArray0:', filesArray[0]);
        jsonFilePath = path.join(imageDirectory, filesArray[0]);
        Log.log('JSON:', jsonFilePath);
        const jsonData = fs.readFileSync(jsonFilePath, 'utf8');

I think my configuration is pretty standard. I put all the pictures in /home/user/MagicMirror/Pictures/ and I've tried many different forms of this path all with the same result.

                {
                  module: 'MMM-BackgroundSlideshow',
                  position: 'fullscreen_below',
                  config: {
                    imagePaths: ["Pictures"],
                    transitionImages: true,
                    randomizeImageOrder: true,
                    slideshowSpeed: 30000,
                    recursiveSubDirectories: true,
                    backgroundSize: "contain"
                  }
                },

Anyone have any thoughts? Thanks!
