This PDF document probably uses a compression technique which is not supported by the free parser shipped with FPDI. (See https://www.setasign.com/fpdi-pdf-parser for more details)

Did you have a look at the link inside the error message? Could it be that you try to process a PDF with a "special" compression-technique?

Edit: if try uploading your document to https://www.setasign.com/products/fpdi-pdf-parser/details/ you can choose which parser you want to use. The workflow_ocr app currently uses the free FPDI parser. If you encounter errors with this one i'm afraid there is not much we can do here (or we'll have to buy a commercial licence ;-) )

Closing since the fdpi-pdf-parser won't be used anymore if #32 is merged.
