```

Start with the fetch entry point in pocket_to_sqlite/cli.py, then inspect save_items in pocket_to_sqlite/utils.py at the failing author_id conversion. Reproduce the shown pocket-to-sqlite fetch command if possible; done means the import handles this Pocket response without the reported ValueError and completes successfully.
