Hello everyone,
Whenever I try to access the layer aggregation tab, I get the stacktrace posted below instead of the content of the page. One of the layer aggregations on this server refuses to be visualised, and returns the following answer when asked for a GetCapabilities: <?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE ServiceExceptionReport SYSTEM "http://myserverurl/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd";> <ServiceExceptionReport version="1.1.1" > <ServiceException> javax.xml.transform.TransformerException: Translator error Translator error</ServiceException></ServiceExceptionReport> I suspect that at least one of the hundreds of layers on this aggregation is somehow broken, but I have no clue on finding out which ones the problem originates from, or even if this is the right hypothesis. I am running Geoserver 2.20.1 on Debian. Stacktrace: org.apache.wicket.WicketRuntimeException: Can't instantiate page using constructor 'public org.geoserver.web.data.layergroup.LayerGroupPage()'.
