Hello,
I want to use Cloud Vision to extract text from PDFs.
However, I only get the error ‘No value returned from OCR Engine’.
I tried different files. Is it because the input is a URL?
Thanks in advance!
Tom
Does it have to be Cloud Vision? Glide has this “Document to Text” column that may fit what you need to do.

Hi Thinh, thanks for the response!
That’s a great idea, yeah. But the AI is supposed to extract specific values from a pretty packed PDF. So I don’t know if extracting the text from it first will do a good job (since the values might be all over the place and taken out of context).
So I thought using an AI that analyses the whole PDF / ‘image’ at once would be better. Maybe the Image to Text module?
As far as I aware, it still has to extract the text first from your document/image, I don’t know how much “positioning” does it need to generate a correct answer. I trialled with something like that in the past, and it works with a bit of prompting (Document/Image to Text => Generate text with first step’s value being the input).
