How to force paperless-ngx to consume signed PDFs

I use paperless-ngx to manage my documents, together with some rules that automaticaly ingest PDFs from my mail boxes. However, I noticed that a recently received invoice from AWS was not ingested as expected. Looking at the logs I found this error message for it: invoice.pdf: Error occurred while consuming document invoice.pdf: DigitalSignatureError: Input PDF has a digital signature. OCR would alter the document, invalidating the signature. I don’t know if a software update brought this refusal to run OCR on signed PDFs, or if AWS simply so long didn’t send me signed PDFs, but I needed to find a way to force paperless to ingest signed things as well as having all of that stuff stored in paperless is a vital part of my accounting workflow....
