Consumer stops work on blank page/failed language detection

When scanning a multi-page document including a blank page the consumer throws the following error and does not add the document to the database:

PARSE FAILURE for /consume/test_xp2.pdf: Language detection failed. Set PAPERLESS_FORGIVING_OCR in config file to continue anyway.

I went the docker way on a MacBook and added PAPERLESS_FORGIVING_OCR="true" to the docker-compose.env file – without success. Ideally, if language detection fails, I would expect paperless to proceed and add the document to the collection without OCRed text? Perhaps I am still doing something wrong? Thanks for any hints!
