The Problem

Hello, i deployed the app with the one click button, "deploy to digital ocean" (App Platform) it's awesome as it's very simple.
But when the app is ready to use, if we go to Cleanups Scans / OCR. We don't have the possibility to upload a document.
For other option it's working. Inside the container : tesseract 5.3 is installed.

On my local environnement with docker compose it's working like a charm !

Do you have any idea ? why OCR is not working out of the box on digital ocean ?

Hey @alexandrevannier! I'm here to help you with any bugs, questions, or contributions you have for the Stirling-PDF project. Let me know how I can assist you!

A similar issue was previously discussed, where the OCR functionality was not working on Digital Ocean for Stirling-PDF version 0.34.0. The solution involved ensuring that the paths for the tessdata locations are correctly set in the Docker setup. Specifically, the tessdata directory should be set to /usr/share/tessdata in your Docker configuration on Digital Ocean. This path change is crucial for the OCR to function properly ^[1][2].

Make sure your docker-compose.yml file on Digital Ocean includes the correct volume configuration:

services:
  your_service_name:
    image: your_docker_image_name
    volumes:
      - /location/of/trainingData:/usr/share/tessdata

Additionally, ensure that the necessary language packs are installed in the /usr/share/tessdata directory. You can download the desired .traineddata files from the Tesseract GitHub repositories, such as tessdata_fast or tessdata, and place them in the specified directory. Remember not to remove the existing eng.traineddata file, as it is required for the OCR to function.
