Why does my upload keep failing when the first row of the CSV is empty? I get the same error every time.

The upload fails because the importer reads the first row as your column names, and a blank row gives it nothing to name the columns with.

With no keys to map values onto, the parser stops before it reaches a data row. Check the header before parsing the rest of the file:

python 
header = next(reader, None)
if header and any(h.strip() for h in header):
    rows = list(reader)
else:
    raise ValueError("The first row has no column names.")

Strip the blank line, or skip it before parsing, and the import goes through.
