From just reading the error it seems that the problem is within your data itself, where you have either specified a duplicate entry in a column that has no duplicates specified, left a row blank where there is a no nulls constraint, or the foreign key cannot reference the source(i.e there might be data missing on one of the fields where the foreign key gets its value).
Might not be that at all, but it's the first thing I would look at
