Single tuple causing cursor.executemany ORA-03147: missing mandatory TTC field #30

I am getting this error when executing the following. Uncommenting the lines below makes it work. So I have concluded if a single tuple in a list is used executemany has a problem. I've got a workaround so not a show stopper. It is not peculiar to this insert as I have tried other tables and differing SQL:-
sql_ins_doc_spell = """
begin
insert into doc.spell_correct (unknown_word, default_word ) values (:1 , :2);
exception
when dup_val_on_index then
null;
end;
"""
spell_correct = []
spell_correct.append(('jick', 'jack'))
#spell_correct.append(('ramana', 'ramona'))
with connection.cursor() as cursor:
cursor.executemany(sql_ins_doc_spell, spell_correct)
connection.commit()
```</div>
