Unable to extract PDF content

I'm trying to extract text from a pdf, but I get the following:

Unable to extract PDF content -> Unable to end a page -> I regret that I couldn't find an OCR parser to handle image/ocr-png.Please set the OCR_STRATEGY to NO_OCR or configure yourOCR parser correctly

My configuration looks like this:

I'm using fscrawler-distribution-2.10-20231023.160816-291

Welcome!

I think you should find a more recent build than "20231023".
The latest I can see is fscrawler-distribution-2.10-20240213.145447-315.zip.

But I don't think that will fix your problem. Could you share your PDF document so I can try it out? If you can't share it publicly, you can send me a private message.

Thank you! I sent you a dm with the pdf doc. Please let me know if more information is needed

So I tried your document and was able to get its content. Something like *** 18 de septiembre de 2013 *** (skipping the rest)...

May be this does not work on windows or that was caused by an old build of FSCrawler?

Could you try with the most recent build?
If this does not work, could you try with the FSCrawler Docker images?

I tried that build and didn't work. However, it worked after using the FSCrawler Docker images. Thanks for the help :grinning:
