I'm using &applyOcr=yes, but there's no indication that any OCR is taking place.
I'm getting back the HTML from PDF text ok, but pages that are images of (clear) text from my PDFs are completely skipped.
I'm using the latest docker image from the notebook.
thanks

Any progress on this issue? We have the same problem.

I've run locally and stepped through the code. The OCR step seems to be returning an empty HTML body. And when I look at the Tika logs, the tika server is throwing an error when attempting to do the OCR. It may be related:
