sqlite3.OperationalError: table sqlite_master may not be modified

[PanosDine]

I get the following error when I try to use the db-to-sqlite command to export my postgres db into a .db file:
sqlite3.OperationalError: table sqlite_master may not be modified

I'm using db-to-sqlite 1.4, sqlite-utils 3.30, and Python 3.10.8. I installed db-to-sqlite with pip install 'db-to-sqlite[postgresql]'.

My command is something like:
db-to-sqlite "postgresql://localhost/my_db" my_exported_db.db --all --skip=django_migrations

Traceback:

The only workaround I found online was this comment by awpears, but that means overwriting the db.py file
