Thanks Tim,
Your remarks about the browser got me thinking.
I *cleared my browser cache* (Firefox), and the PDF error disappeared,
and I was/am able to download PDFs as an anonymous user.
Thanks for your help.

Hi Eric,
As noted in the DSpace Documentation, both COAR Notify and Quality
Assurance are disabled by default. You have to manually enable both
via a configuration setting. See the configuration docs for each at:
https://wiki.lyrasis.org/display/DSDOC8x/COAR+Notify
https://wiki.lyrasis.org/display/DSDOC8x/Quality+Assurance
Based on the snippet of the error you've shared, it almost sounds like
you have a custom PDF viewer or something in place? The error says:
Message: Invalid PDF structure. viewer.mjs:12365:13
I'm not sure what "viewer.mjs" is? I don't believe that is included
in DSpace by default.
So, this all seems odd to me, as I'm not sure what is attempting to
open your PDF files. By default, DSpace will just stream the PDF to
your browser (which should trigger a download unless your browser can
open up PDF files).
As a sidenote, I also can verify we don't see this same behavior on
our demo site (running 8.1) at https://demo.dspace.org

I think they are causing PDF downloads to fail for Anonymous users.
Starting with 8.0, *as an Anonymous user*, I've been getting

My guess is that somehow COAR Notify - LDN Services

and Quality Assurance
<https://wiki.lyrasis.org/display/DSDOC8x/OpenAIRE+Integration>
features have been enabled by default,
and that is causing these errors. I also note that 2 new Solr
cores are included in DSpace 8.x, *qaevent* and *suggestions*.
I'm pretty sure I don't need any of this LDN / Quality Assurance
stuff. And I'm hoping if I disable them, Anonymous users
will once again be able to download PDFs.
Thanks.
