Adobe Extract API: Some text is extracted as images.

[Guest]

I am developing a system that uses the Adobe Extract API to extract sentences from PDF file in JSON format.

When I hit the Adobe Extract API against the PDF file, parts of the document where was the text was extracted as image.

In the image below, red part is extracted as text (expect result).
But blue part was extracted as image (unexpected result).

This is the code I used:
https://github.com/adobe/pdftools-extract-node-sdk-samples/blob/main/src/extractpdf/extract-text-tab...

This is the PDF file. Page of the image above is on page 59:

JP-N-KP-EPI-2000063_イーケプラ経口剤IF_rev18.pdf (ucbjapan.com)

The language of the PDF is Japanese. The PDF file is not a scanned paper file, but a PDF file of digitally created data.

Is there any information or solution for this?

@Deleted User Did you find any solution to this outside the Adobe Community?

Had encountered a similar problem, but there's no resolution to it.
