files in shared directory now showing in web page. Server returned 500 error

[turboc1208]

Description
Server is returning a 500 error when I try to view files that I have uploaded to the shared directory on the Pi

Reproduction Steps
use the upload button on the file page to upload a file from my Mac to mariner.
The file is copied to the usb_share directory correctly
The web page times out looking for files and returns a 500 error.

Expected Behavior
The server should list the files in the usb_share directory so they can be selected to print.

Screenshots / Logs
If applicable, attach screenshots or logs to help explain your problem.

Details:

• Mariner Version: 0.2.0-1
• Printer Model: Elegoo Mars Pro
• Raspberry Pi Model: RPI with Beagle installed in order to get correct version of Python.

Additional context
I have not setup or attached the printer itself yet, but I wouldn't think that would matter on the File page.
