We have a workflow in Open Journal Systems where we use Pandoc to convert word documents to EPUB, and then display them with an embedded EPUB app (Bibi).
Our resulting EPUBs work fine with both debuggers and viewers like calibre. They work in Bibi, but only when they are reduced to a certain length. Whenever the files exceed approx 100 lines or 600 words, Bibi claims:
TypeError: Cannot read properties of undefined (reading ‘getAttribute’)
Meanwhile, the same documents works when converted to EPUB using other converters, or when I reduce the length (length, not size in bytes-- I've tried with graphics, still works). It suddenly works when I reduce the length by removing pure paragraph text, even though all the formatted elements (abstract, references, etc) are the same.
I recognize that this problem is very specific to the interrelation pandoc <-> Bibi, but I'd be grateful for general troubleshooting suggestions.
Thanks in advance,
Peter
