<p dir="auto">For a project of mine I usually head over to the customize page to create a bundle. I check off some stuff I don't need and get the resulting zip file for inclusion in the project. Now, after the 2.2.2 release there's a error.txt file in the CSS directory included that reads</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="A less error occured trying to build your bundle. You've likely entered an
invalid input into the less variable field. Check your syntax and try again!

thanks!
