I have configured a simple email field in a simple content type. The email field is NOT set as required.

"Mail": {
      "type": "email"

If i Post an empty “Mail” I get the error “Mail cannot be empty”.

I had the same problem. I solved just sending a null instead of an empry array in the email field.
