Good day, guys! I am trying to import 1 row of data to ERPNext. I am getting an error, see below
self.name = make_autoname(self.naming_series + '.####') TypeError: unsupported operand type(s) for +: 'NoneType' and 'unicode'
Please advise on this. I already did a format check and no asian characters are present on my .CSV
Let me know if there are other things I need to check with the format. Thank you in advance. 
Hey sorry I haven’t gotten to play with the csv importing functions a lot.
Also, you didn’t mention what doctype you are trying to import or any sample data from the csv.
However, that error says that the naming_series field is “None” so it can’t append None to a unicode string. Check your csv and see if that field is set or look into other doctypes to see what they export.
you got a point. What is lacking is the field (column) Series in your template, ex. for Employee it should have EMP for column Series in each row
