trying to import data from mysql but failing

[aminbaig]

I have configured both mysql and clickhouse, when I try to import data I get the following error:

Please advise.

Try to add
row[key] = '' if row[key] is None else row[key]
in /usr/local/lib/python3.6/site-packages/clickhouse_mysql/writer/chwriter.py
77 line

a piece of code

           for row in event_converted:
                for key in row.keys():
                    row[key] = '' if row[key] is None else row[key]
                    # we need to convert Decimal value to str value for suitable for table structure
                    if type(row[key]) == Decimal:
                        row[key] = str(row[key])
                rows.append(row)
