In vendor/magento/module-customer/Model/FileProcessor.php line 199 there is unset($result['path']);
This is required by the upload function in vendor/magento/module-customer/Model/FileUploader.php

commenting out line 199 results in the file appearing in the customer form, however clicking the link results in a 404 error

Hi @stevenlavine
How did you create the file upload attribute? Please share install script that add the attribute.
And please could you share a code, that introduce this attribute in to CMS (xml or/and phtml files)
