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: 2021-09-14 15:24:22,198 WARN unknown unknown org.dspace.discovery.SolrServiceImpl @ We have a collection or community admin with ID:
