Sure. I have attached the files "mwe-data.org" and "mwe-export.org".

To reproduce, save both files in the same directory. Then open mwe-export.org, navigate to the "Export script" heading, and evaluate (Ctrl-C Ctrl-C) the shell source block.

Expected output: a generated html file containing the fruits and vegetables from the mwe-data.org file.
Actual output: Lisp error: (wrong-type-argument stringp nil), details as in my first message.

Compare on the other hand if you navigate to the "Fruits and vegetables" heading and evaluate the emacs-lisp code block, it outputs a list of fruits and vegetables in a results drawer.

OK, thanks for the insight. I haven't figured out where things are going wrong. But a possibly related issue is that lately, when I open an org file for the first time, org-mode does not load automatically. If I close the file and reopen, org-mode loads as expected.

Best regards,
