Hi @raphaelyancey! I'm Dosu and I’m helping the Stirling-PDF team.

The error means Stirling-PDF expected an OCR output file that wasn't created. This is often due to a failure in the OCR subprocess (like Tesseract) or a temp file/permissions issue in Docker. Recent updates have improved temp file management and permissions, so upgrading to the latest version may help if you’re able to do so cite.

Here are some steps to troubleshoot:

• Make sure your Docker container has write access to /tmp. Permission issues can prevent file creation.
• Check the full container logs for any errors or warnings before the NoSuchFileException—look for Tesseract or OCR-related failures.
• Try running OCR on a simpler PDF (without CamScanner watermark) to see if the issue is file-specific.
• If the problem persists, enable debug logging for more details, or share earlier log lines from the OCR attempt.

The tessdata volume mapping looks correct, but if you use custom language packs, double-check that they’re present and readable in the container cite.

Recent changes to temp file handling and OCR process management may resolve this, so testing with the latest image is recommended cite.

To reply, just mention @dosu.
