I just tried this and it worked without issue.

Some considerations:

1) tell it to extra t the data (in a new session) does that work?

2) if it doesn't, could there be something up with the PDF?

As many commentors suggested, this works well with Gemini so there is likely a missing variable in play.

Share your prompt and the PDF and let's see if we can determine what.

Long shot, but I wonder if an image of the pdf would do better if it did get unstuck on internal formats.

It definitely does. PDF is a vector-based image format historically, and all add-ons that make it behave a bit more sane as a text-oriented document format are optional, so your mileage using tools like pdftotext will vary greatly depending on who created a given PDF.
