Error when trying to create TSV file

[Gurey]

Trying to create a TSV gives me an error.

endpoint: localhost:9292/ocr

with payload:

{
  "img_url": "http://bit.ly/ocrimage",
  "engine": "tesseract",
  "engine_args": {
    "config_vars": {
        "tessedit_create_tsv": "1",
        "tessedit_pageseg_mode": "1"
    }
  }
}

Gives me: Error processing image url: . Error: Could not find outfile. Basename: /tmp/785ad93e-2721-4fd1-7892-b78ffc442ae0 Extensions: [txt hocr]

Does it work if you remove the "config_vars"?

The relevant code is here:

I wonder if tesseract is writing to a file extension that OpenOCR isn't expecting.. looks like OpenOCR looks for .txt or .hocr

Hi! thank you for getting back to me.

these 2 requests works fine:

{
  "img_url": "http://bit.ly/ocrimage",
  "engine": "tesseract",
  "engine_args": {
    "config_vars": {
        "tessedit_create_hocr": "1",
    "tessedit_pageseg_mode": "1"
    }
  },
  "psm": 3 
}

{
  "img_url": "http://bit.ly/ocrimage",
  "engine": "tesseract",
  "engine_args": {
    "config_vars": {}
  },
  "psm": 3 
}

I just tried to run tesseract in my terminal with the command tesseract pic.jpg out tsv and that gives me a file named out.tsv

Ok I think the fix is pretty easy, it just needs to look for files with .tsv extension. Are you able to submit a PR?
