Jan and Tim, I'm going to offer some extra information that might help future people. I was (am) testing this on a development server with self-signed TLS certificates and that was also causing this error to occur. Since am on a development server, I switched everything to SSL=false, and HTTP instead of HTTPS and that mostly solved the problems I was having. I will pursue the problem later, but I may need to add my organization's internal Root CA Certificate to my development server and continue testing.
Of course I had to update all of my settings to match (local.cfg, environment.dev.ts, etc) I don't think a LetsEncrypt Cert would cause this problem, but you never know. --Joel Richard Smithsonian Libraries and Archives On Monday, October 4, 2021 at 1:08:06 PM UTC-4 [email protected] wrote: > Hi Tim, > > the files are identical (I also tried a copy of environment.dev.ts to > environment.prod.ts), which did not help. > > It looks very strange for me, the guide > https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-%22No_linkssectionfoundat...%22errorfromUserInterface > > probably will be useful. > > Installed on Debian. > > Jan > > > On Monday, October 4, 2021 at 5:32:04 PM UTC+2 Tim Donohue wrote: > >> Hi Jan, >> >> We have a guide for that error here: >> https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-%22No_linkssectionfoundat...%22errorfromUserInterface >> >> That said, your REST API at https://sulis53.zcu.cz/server/ "looks >> correct" to me, and you can see that it has a "_links" section in the >> response. >> >> Therefore, I highly suspect something is wrong with your >> environment.prod.ts.
