Hello all, I'm doing a local test upgrade from 8.1 to 8.3 on MacOS (Solr version 8.11.4) and I have run into an issue that I just cannot get my head around.
Searching is not working properly, resulting in some lists not rendering etc. Browse functions work. Search index is created correctly and I can also access it, and it looks ok and is fully searchable from Solr admin, without issues. dspace log: 2026-02-13 09:05:33,056 ERROR 2654b549-738c-46dd-8fb3-24a02ba05b5e 189ac324-0aad-437f-ba3f-746d2b764ad9 org.dspace.app.rest.repository.DiscoveryRestRepository @ Error while searching with Discovery org.dspace.discovery.SearchServiceException: Error from server at http://localhost:8983/solr/search: Unknown encoder: html at org.dspace.discovery.SolrServiceImpl.search(SolrServiceImpl.java:784) at org.dspace.discovery.SolrServiceImpl.search(SolrServiceImpl.java:763) at org.dspace.app.rest.repository.DiscoveryRestRepository.getSearchObjects(DiscoveryRestRepository.java:107) at org.dspace.app.rest.DiscoveryRestController.getSearchObjects(DiscoveryRestController.java:156) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:104) at java.base/java.lang.reflect.Method.invoke(Method.java:578) solr.log: 2026-02-13 09:05:33.018 INFO (qtp1341706533-85) [ x:search] o.a.s.c.S.Request [search] webapp=/solr path=/select params={q=*:*&fl=dateIssued.year,search.resourcetype,search.resourceid,search.uniqueid,database_status&start=0&fq=(search.resourcetype:Item+AND+latestVersion:true)+OR+search.resourcetype:Collection+OR+search.resourcetype:Community&fq=-withdrawn:true+AND+-discoverable:false&fq=location:l67384c88-38f3-4f99-b727-e16535ef2def&fq=location:l67384c88-38f3-4f99-b727-e16535ef2def&fq=&fq=dateIssued.year:[*+TO+*]&sort=dateIssued.year_sort+desc&rows=1&wt=javabin&version=2} hits=1 status=0 QTime=1 2026-02-13 09:05:33.021 INFO (qtp1341706533-87) [ ] o.a.s.s.HttpSolrCall HttpSolrCall.init(http://localhost:8983/solr/search/select?null) 2026-02-13 09:05:33.053 ERROR (qtp1341706533-87) [ x:search] o.a.s.h.RequestHandlerBase org.apache.solr.common.SolrException: Unknown encoder: html => org.apache.solr.common.SolrException: Unknown encoder: html at org.apache.solr.highlight.DefaultSolrHighlighter.getEncoder(DefaultSolrHighlighter.java:360) org.apache.solr.common.SolrException: Unknown encoder: html at org.apache.solr.highlight.DefaultSolrHighlighter.getEncoder(DefaultSolrHighlighter.java:360) ~[?:?] There is no HtmlEncoder in the Solr configs, but I don't think there should be either, and I guess this is something else going wrong? If someone could give me a hint on what I should be looking for it would be really appreciated.
