After upgrading to version 8.0 of the webviewer we are now noticing a lot of Could not load type ‘APPortalUI.Web.HttpHandler.PdfHttpHandler’. exceptions in our .NET MVC application. PDFs are still loading. But it is looking for this URL, which does not exist (the dk parameter changes each time, the rest seems to be the same): /Documents/FileViewerOrPublic/APPortal.axd?rt=2&dk=004D94928O6km6t3sl8ww4fFyWm1pxvgn&cn=ctl02_PdfControl&un=ctl02%24PdfControl&v=2.32.5.0
Please provide a link to a minimal sample where the issue is reproducible:
Thanks for contacting us for support. Since there is not much we can tell by looking the Frontend application, we need your assistant to help us to narrow down the issue:

Can you be more specific? If you see this in your log, can you copy the entire log message?
For the URL:
Is this request comes from WebViewer library? If so, can you find which file is making this call?

Yes, I believe this request appears to be coming from the WebViewer library, as nothing in our code hits APPortal or APPortal.axd directly. No, I don’t think I can find which file is making the call (I haven’t been able to reproduce the problem, though we have thousands of these errors in our logs over about 3 hours).
The first part of the URL (/Documents/FileViewerOrPublic) is from us. That’s the URL we use to serve up your webviewer; it returns the DIV (via JavaScript) and your JavaScript that ultimately loads .
I couldn’t find anything related to APPortal.axd or APPortalUI or APPortal in WebViewer JavaScrit Library. I suggest you do a global search in your codebase to find this out.
Also, are you using and PDF SDK? If so, what language are you using?
