Yes, of course: #+begin_src org ,* Simple illustration of nil link error message In table [[mytable]], there are some numbers ,** the table :noexport: ,#+name: mytable | x | y | |---+---| | 1 | 1 | | 2 | 4 | ,#+TBLFM: $2=$1^2 #+end_src There is a reference to a table which is in a subtree that is not to be exported. The error message is user-error: Unable to resolve link: nil This ECM may appear contrived but, when working with a large document, it is easy to comment out or exclude sections that, it turns out, have material within that is referenced from elsewhere. This is difficult to track down when exporting. If the error message had "nil" above replaced by "mytable", it would make all the difference!
