Hi Tim, I have used your Dockerfile and built a docker image. It is working perfectly fine on my setup.
I have even tried various other options for tika-app and changed tika config and they also work fine. I have tried to set a explicit path for tesseractPath and not setting as well. That too works. sandeep@SK-UBUNTU:~/tika-docker-play$ docker run -it tika-docker DEBUG [main] 11:48:48,569 org.apache.tika.parser.external.ExternalParser exit value for /usr/bin/tesseract: 1 DEBUG [main] 11:48:48,570 org.apache.tika.parser.ocr.TesseractOCRParser hasTesseract (path: [/usr/bin/tesseract]): true ... <Logs about ImageMagick missing> ...

This can add greatly to processing time. If you do not want tesseract to be applied to your files see: https://cwiki.apache.org/confluence/display/TIKA/TikaOCR#TikaOCR-disable-ocr DEBUG [main] 11:48:49,702 org.apache.tika.parser.ocr.TesseractOCRParser Tesseract command: /usr/bin/tesseract /tmp/apache-tika-3898071413980732955.tmp /tmp/apache-tika-1645794913082823345.tmp --psm 1 -l eng -c page_separator= -c preserve_interword_spaces=0 txt DEBUG [Thread-5] 11:48:50,274 org.apache.tika.parser.ocr.TesseractOCRParser DEBUG [Thread-6] 11:48:50,275 org.apache.tika.parser.ocr.TesseractOCRParser Tesseract Open Source OCR Engine v4.1.1 with Leptonica ... ... <title>Presentation1</title> </head> <body><div class="page"><p/> <div class="ocr">Happy New Year 2003! </div> I have even tried using the same commands on Ubuntu VMs which show the issue, that too worked fine. So definitely something is wrong with our application (or its configuration). As I am still facing the issue, I will try to investigate further on my own. Thanks a lot for your help.

To be clear, I trust you are having your problem! Can you work with that repo and see if you can get it to fail? Maybe add a stripped down version of your tika-config.xml?
