If you look carefully at the error response it contains clues: Bummer! Didn't get the right content in the groups. Last name was "Perotto,", first name was " Pier Giorgio".

The last name contains a comma at the end, and the first name has a space at the beginning. These characters separate the names, but the regex should not include them as part of the names.
