When running detect-secrets scan --only-allowlisted on a directory containing empty files (for instance a tracked and empty __init__.py), a ValueError is raised:

ValueError: not enough values to unpack (expected 2, got 0)
This is because the provided iterator lines is empty.
A simple way to fix this would be to handle the exception in scan_for_allowlisted_secrets_in_file with:
try:
for lines in _get_lines_from_file(filename):
yield from _scan_for_allowlisted_secrets_in_lines(enumerate(lines, start=1), filename)
break
except IOError:
log.warning(f'Unable to open file: {filename}')
return
except ValueError:
log.warning(f"Unable to scan file: {filename}. Ignore if it is an empty file.")
