Custom Excel App No Longer Working

Anvil Q&A
1

What I’m trying to do:
About a year and a half ago, I created an app that creates a spreadsheet with a table of contents page, custom sheets, and custom columns. Then it hyperlinks everything together. This used to work, but now I am getting the following error:

Code Sample:

OSError: [Errno 30] Read-only file system: 'test.xlsx'
at /usr/local/lib/python3.10/zipfile.py:1251
called from /home/anvil/.env/lib/python3.10/site-packages/openpyxl/writer/excel.py:291
called from /home/anvil/.env/lib/python3.10/site-packages/openpyxl/workbook/workbook.py:386
called from excel_creation_module, line 83
called from home, line 23

Any ideas? My google-fu is failing me…
