Python scraperwiki for CSV

My Python CSV scraper scrapes single CSV file, and in Morph.io console output for last run I can see it reads file when I comment out part for sqlite save:

scraperwiki.sqlite.save(unique_keys=['OIB', 'Rb.'], data=record)

But with any combination I get error that column does not exist.

save statement with column named “Rb.” is numeric and should be unique, other unique value is column named “OIB”, and true change is actually recored in last update date (last column). I don’t understand why it does not detect colum named “Rb.” or “OIB”.

Can somebody check why I’m unable to save result in sqlite?
