Could you please tell like the below value belongs to which column in list as well as in DB?
27AAAFS7156D1Z9
Edit - Found that it is for Vendor GST Number. Does this column in DB was created as varchar only or was it previously configured as INT??
Did you tried creating a new column with varchar property and update to that column instead of existing one?Are you facing the same error?
Also check the syntax of DB insert command is correct and matching with the values and columns. Considering the number of fields are more - it is worth to confirm that as well
