DSpace 7.6.1 - Browse by Issue Date - selectively stuck on Loading...

[Tomas Hajek]

Hi all, 

   We recently went live with DSpace 7.6.1 on Red Hat Enterprise Linux 8 and are seeing an issue with the "Browse by Date" function.

   From the home page selecting "Browse by date" causes an indefinite "Loading page...".  On most  Communities, Subcommunities and Collections the "Browse by Date" seems to work correctly.   You can see this at https://our.oakland.edu

   I read over the issue at https://github.com/DSpace/dspace-angular/pull/1535 ("Browsing by issue date" is stuck on loading) and am assuming that we might have a data issue with some items but not sure how to track them down. 

   Does anyone have a suggestion or how to better diagnose this?  Watching the console or network interaction in the browser dev tools does not give me anything obvious and I don't see any errors in the dspace.log or Apache Tomcat 9.0.85 logs.

   Is there maybe a database table and field I might need to be looking at?

Thanks for any help.  I really appreciate it.

-Tomas

Hi Tomas,

If you are still encountering this, then you might want to look more closely at "dc.date.issued" field values (as that's the metadata field used in Browse by Date).   It might be some sort of bad data that is causing an unexpected issue.  You might be able to narrow down the issue by trying to use the "Browse by Date" for specific Communities/Collections (on the Community/Collection homepage) to see if specific Communities or Collections are loading fine while others are failing.

You also may want to use the troubleshooting guide to look for possible errors being thrown in the UI or backend.  Those can be major clues in what is going on. https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)
