PDF Export URL Join Error

Since updating to v14.7, when trying to use the PDF export plugin, i get the following exception when using the function:

“TypeError: Cannot read properties of undefined (reading ‘join’)

i also tested this on a quickly set up VM and it worked fine without any additional extensions installed.
Just wondering if this is a Bug or if my environment got nuked with the last update.

I did reinstall the extension a few times as well.
