Hello Swapnil,
Do you get complete list of error after pressing "YES" in dialog ? Could you please post data from it ?
It looks like some data could not be added to the database. The cause of that could be database field size or field type.
As well if it possible upload this file as well I will try to check if I am able to get same issue on my side with default database structure.
Thank you
Regard,
Artiom
