SiteJet Builder publish error - "File name too long"

Symptoms

Attempting to publish a Sitejet website gives an error similar to the following:

CONFIG_TEXT: The publication process failed due to following exception: Cpanel::Exception::IO::FileOpenError/(XID zv4q6n) The system failed to open the file “/home/USER/public_html/domain.tld/[...].woff2” because of an error: File name too long

Cause

When using Sitejet's tools to customize a font it provides, each feature is appended to the URL for storage. If too many settings are enabled on a chosen font, it can result in the font's file name becoming too large for when cPanel attempts to retrieve the font from Sitejet when publishing.

Resolution

Manually upload the font that you would like to use into Sitejet and use a shorter name. Sitejet provides steps on this process here:
