Your problem is that the result argument has this sort of form:

(:thread "00000000000029c5"
 :timestamp 1658007025
 :date_relative "Sat. 22:30"
 :matched 3
 :total 5
 :authors "David Bremner, Jon Hurst| inwit"
 :subject "Feature request: show destination in tree view when
 appropriate"
 :query ("id:87ilnx5mxq.fsf@tethera.net id:877d4dry2i.fsf@hursts.org.uk
         id:87cze468zy.fsf@tethera.net" "id:87a699e6wn.fsf@hursts.org.uk
         id:CLJIU9081RIS.3M4YBKDJ2UJ3O@bisio")
 :tags ("inbox" "replied")
 :orig-tags ("inbox" "replied"))

So there is no :headers and :authors has multiple entries. I guess what
you are looking for is that if the only author is yourself, replace the
author with the "To: ..." version, in which case you would have to use
the :query section to find that.
