Hi Thiago, It sounds like the SIte object didn't initialize in your database properly. That can sometimes occur if something fails in the installation or setup of your database.
You should verify that all database migrations ran successfully on your database by running this from commandline (in the [dspace]/bin/ folder): ./dspace database status It should report every migration as either "Success" (ran successfully) or "Out of Order" (ran successfully but run out of numerical order -- sometimes happens via upgrades). If anything is failed or Pending or Ignored, then you need to complete all the migrations via : ./dspace database migrate ignored If everything is succeeded, then you can force the "Site" object to be recreated by running ./dspace database migrate force After running any of these commands, you should verify no new errors appear in your dspace.log. More docs on all these commandline options are at https://wiki.lyrasis.org/display/DSDOC7x/Database+Utilities Tim On Tuesday, August 22, 2023 at 12:23:08 PM UTC-5 Thiago Camelo wrote: > > Hi Tim, thanks for the answer. > I followed the suggestions on the troubleshoot guide and after setting up > the java trace i got this: > > > *java.lang.NullPointerException: Cannot invoke > "org.dspace.content.Site.getID()" because the return value of > "org.dspace.content.service.SiteService.findSite(org.dspace.core.Context)" > is null ...* > There's nothing similar to this in the common installation issues article > nor in the backend documentation (as far as i looked).
