"Wrong number of arguments: nil, 0" error when exporting a table with caption to ODT

"Wrong number of arguments: nil, 0" error when exporting a table with caption to ODT

[Perl Ancar]

Dear all,

I tried exporting a document with table that has caption to ODT and it
failed with this error message:

    OpenDocument export failed: Wrong number of arguments: nil, 0

Sample document:

    #+CAPTION: some caption
    | row1 |

Export is successful when caption is removed. Export is successful for
image captions. Export to HTML or Markdown is successful. Org-mode version
8.2.10, Emacs 25.2.2 on LinuxMint 19.

Any pointer?

Trying with the latest release of Org (9.3.6), I exported this without
hitting the above error, so upgrading will likely resolve the issue for
you.

If upgrading doesn't work for you (or you'd just like to investigate),
doing "M-x toggle-debug-on-error" and getting a backtrace could be a
good place to start.

Unfortunately after M-x toggle-debug-on-error I'm not getting relevant
additional messages in the *Messages* buffer (I read that messages will
appear in the *Warnings* buffer, but I see that there is no *Warnings*
buffer created):

    Debug on Error enabled globally

    You can run the command ‘org-odt-export-to-odt’ with M-x -od-t RET

However, when trying to upgrade org, I try exporting under "emacs -q" and
this error does not happen. So I'll need to comb through my years-old
~/.emacs to try to figure out what causes this error.

Ah, sorry for the unhelpful suggestion.  It looks like that error is
being caught (which I should have guessed from the "OpenDocument ..."
prefix):


  (defmacro org-odt--export-wrap (out-file &rest body)
    [...]
       (condition-case err
           [...]
         (error
          ;; Cleanup work directory and work files.
          (funcall --cleanup-xml-buffers)
          (message "OpenDocument export failed: %s"
                   (error-message-string err)))))

So to see the error, you could either remove that error handling or
tweak it to re-throw it:

    (signal (car err) (cdr err))
