I am setting up the action to send email to the node author, node is posted by anonymous user, but there is email field in the node. the field token is "[node:field_story_email]" , but I got error message below when I am using this token on the "Recipient"

"Enter a valid email address or use a token e-mail address such as [node:author:mail]."

Is the email field token not supported for the Recipient ?
