Files downloading as 1 KB instead of expected size

ddp.download_files(files_df, "dbs/neighborhood_patterns", skip_exists = True)

The same command previously downloaded a few files with normal file sizes. Now it only downloads many 1-KB files, which I believe indicates an error. Does anyone know what might be causing this or how to fix it?

I am accessing Foot Traffic / Neighborhood Patterns via ddp in Python.

Thanks in advance!
