[Zhongping Yan]

Hi,

I built DSpace backend and frontend on my local machine. Deployed backend on Tomcat. I logged in DSpace UI, but cannot load its Home page. Looked at the beckend log file dspace.log. I fount an exception always occurred when I went to Home page through URL http://localhost:4000/home. It cannot go to Home page when I was in Profile page or MyDSpace page by clicking the DSpace logo or Home breadcrumb. The exception and log into in logs are as below:

Hi Zhongping,

The main error is saying that DSpace cannot find your "Site" object in the "site" database table.  See this part of your long error thread:

2021-09-14 15:27:10,619 ERROR 6f11b865-8655-4de3-9021-c43413a9d74d cb806e95-e747-4094-8a27-c1fcc03ad0c7 org.dspace.app.rest.exception.DSpaceApiExceptionControllerAdvice @ An exception has occurred (status:500)

Make sure your database is completely up-to-date. On the backend, check './dspace database info' is showing that all migrations are either returning "Baseline", "Success" or "Out of Order" (which also means it was successful, but it just ran out of normal order).  

If there are any that have NOT​ run, this means you forgot to run "./dspace database migrate" (if it was a fresh install), or "./dspace database migrate ignored" (if it was an upgrade). Or, if you did run that command, it must have thrown an error in the logs and refused to complete.

Hopefully that'll help solve the issue.  If not, let us know on this list if you need more help.

Tim

Hi Tim,

Thank you for your reply. When I installing backend, I ran command "./dspace database migrate". After read your email, I did query in dspace database "select * from site" and got nothing.

Below is the result of command './dspace database info'.

Please give me more advices. Appreciated.

Hi Zhongping,

That's really odd, as the Site object is supposed to be created automatically after​ all Migrations run by our SiteServiceInitializer: https://github.com/DSpace/DSpace/blob/main/dspace-api/src/main/java/org/dspace/storage/rdbms/SiteServiceInitializer.java#L41

This is the first time I've ever heard of database migrations succeeding​ while the SiteServiceInitializer somehow fails​.  Is there any chance you have your 'dspace.log' from when you installed DSpace 7 to see what error is thrown by the SiteServiceInitializer?

Unfortunately, since we've never seen this happen, there doesn't yet seem to be a script to create the Site object in a different way.  Since it sounds like you've not added any content, you may want to drop your (empty) database and try the entire "./dspace database migrate" option again (paying close attention to the dspace.log to see if it again throws errors when creating the Site object).  At the very least that'd give us more information on what could be going wrong in your installation such that the Site object doesn't get initialized properly.

Tim

Hi Tim,

I dropped the database and did "./dspace database migrate" on a new database. It worked and I can reach to Home page. I created/edited community, collection. My local DSpace works well.

Thank you so much for help.

Zhongping

[Zhongping Yan]

forgot telling you that I don't see error/exception in previous logs when I did database migrate. This time I checked site table and saw a row in it.

Thanks again.

Zhongping

[Tim Donohue]

Glad to hear it, Zhongping!

As a side note: If anyone else ever hits this same problem in the future, I'm working on a way to allow anyone to re-run​ any of these post-migration scripts (like the SiteServiceInitializer) at any time just in case one randomly fails (like seems to have been the case here). See https://github.com/DSpace/DSpace/pull/7945   I'm hoping this will be in 7.1...as this would let others solve this problem without having to drop the entire database & rerunning the migration on a new/fresh database.

Hi Tim,

From dspace log files, I found warnings like below. I saw many instances of this warning in the dspace.log file, not just at running "./dspace database migrate".

I installed PostgreSQL 13.4 while Flyway doesn't support this version. This might be the reason why table site was not migrated. Hope this info help to solve the issue.

Same issue with me for dspace 7

Drop database / Migrate command made sure dspace is working smoothly
