Export via org-dispatcher fails while M-x org-pandoc-export-... works as expected

[emwal]

Expected behaviour: Exporting org-buffer viaorg-export-dispatch and p (pandoc) + l (to latex-pdf and open) should produce the same results as M-x org-pandoc-export-to-latex-pdf-and-open.

Observed behaviour: M-x org-pandoc-export-to-latex-pdf-and-open. works flawlessly, while org-export-dispatch fails with "Symbol’s value as variable is void: org-pandoc-options-for-nil" (or at least I think this is the relevant part. The error message is way longer.).

Does anybody have a solution for this? Thank you for your help!

Hope, it helps! Thank you!

It does not look like a full message. You can try M-x toggle-debug-on-error. Then, the backtrace should appear in a separate window, where you can copy it from in full.

[emwal]

M-x toggle-debug-on-error does not trigger. My Messages buffer looks like this.

Debug on Error enabled globally
Initializing asynchronous export process
Process ‘org-export-process’ exited abnormally
Debug on Error disabled globally

Note the asynchronous export process instead of the synchronous. I set org-export-async-debug to t and tried again with the same result.

[emwal]

And org-pandoc-menu-entry has the following value:

[emwal]

I set org-export-in-background to nil and it worked as expected. Apparently the error is with the asynchronous export.

[yantar92]

Thanks for investiating! I can see how it is a problem.
