Using ocrd.sif built from ocrd/all:maximum at 2023-06-13 18:00 CEST

Tried with the image here:

... and essential the same workflow as in run.sh. See complete workflow at bottom.

Not sure if this is related to https://github.com/qurator-spk/eynollah/issues/106.

For OCR-D, please downgrade to https://github.com/qurator-spk/eynollah/pull/108 – or use the current version of ocrd_all, just released today.

If the problem persists, please report with a test data (input image) directly to eynollah repository.

Updated ocrd.sif today 14:12 CEST

approx. the same error:
