Google Scholar citation_xx metadata tags no longer visible to the crawler

Describe the bug

We received this message from Google, we are running 7.6.2 for reference

I hope that this message finds you well! My name is Ollie, and I work at Google Scholar.

I'm writing regarding krex.k-state.edu -- I hope you're still the right contact.

The indexing system recently alerted us that the citation_xx metatags (which Scholar uses for indexing) are no longer visible to the crawler. It's possible that a recent update resulted in the metatags being loaded by JavaScript and not server-side rendered.

For example:
view-source:https://krex.k-state.edu/items/19dfeba9-33a1-4173-98fd-170115ec868f
view-source:https://krex.k-state.edu/items/1f6701b3-08fa-459a-8d1d-5f1b3c8ea9dc

both show the citation_xx metatags in a browser, but not for the crawler.

Would it be possible to take a look?

Let me know if you have any questions.

Many thanks in advance,

@misilot : we'd need more information here. It looks, to me, like the "citation_*" tags exist in your server-side rendered HTML. If I "Disable Javascript" in Chrome, and access one of those pages, I can "view source" and see the tags (search for "citation_title" for example).

This looks like the same behavior that we see on https://demo.dspace.org/

So, I don't see a bug here. Or, I don't have enough information to reproduce it.

I can reach out to Google and see if I can get more information or ways to for us to reproduce what they are seeing.
