I’ve just set up a production site on flywheel, but for some reason the site isn’t able to load resources from the node_modules directory. All other stylesheets and scripts have been successfully loaded. This is only an issue on production. I’ve already tried changing the permissions on the files in question, and changing the loading order in functions.php.
If so, can you show us the line of your functions.php that loads it and a print of your theme folder where the files are?
Have you checked for the references to be sure they are right?
