Hi @Krishnanunni, That's right, I had selected the temporary schema in
the dropdown as in your screenshot, and selected the email expression
there as well. I haven't found the solution to this error yet 😞 it
seems right to me, but I'm thinking that maybe this email field doesn't
work for deduplication, even though all of the profiles that I am
uploading has it and the column is well identified. Thank you for this
possible solution 🙂 Have a great day!
