So publishing cannot have the target directory be the same as the source directory, it would seem? Having a different directory for :publishing-directory makes publishing work. I still do not understand the error, however.
My original question remains: can we create an index for HTML export without using publishing? Thank you, eric -- : Eric S Fraga, with org release_9.5.4-623-gc66bdb in Emacs 29.0.50
