all the attributes mapped correctly but while uploading data into dataset it shows some error status shows as failed.
But it's not getting error while uploading 5 or few records into the data set.
I tried followed approaches but also getting failed to ingest
1.Created custom field as email and declared string as datatype also getting the same error.
I think its not supporting bulk data like that I'm using sandbox instance
Is there any different approach for it or any solution for it.
Please have a look on attached file.
