I have a content type called Help Wanted. I have another content type called Reply to Help Wanted. The reply content type includes an entity reference field that contains a node reference to the original help wanted ad being replied to.
I am trying to use Rules to send an e-mail when a reply is posted to the author of the original Help Wanted post.
However, I don't know what to put in the To field of the Send mail action. I tried the following:
But this token didn't work. I also tried several other variations to no effect. Is it possible to use tokens to get the author's e-mail of a node linked by entity reference? If not, how do I get the author's e-mail via the entity reference?
