Hi guys,
So let me tell you scenareio so, I have cloned the repo and build the open CE from source and move this generated OpenKM.war file in TOMCAT_HOME/webapps. (I have taken tomcat-8.5.69.zip form SourceForge)
After doing this I started the tomcat server TOMCAT_HOME/bin/startuop.sh.
and I got the below browser screen.(I am using Ubuntu - 22)

The error is related to AJP connector
23-Apr-2024 17:02:39.827 SEVERE [main] org.apache.catalina.core.StandardService.startInternal Failed to start connector [Connector[AJP/1.3-8009]]
Caused by: java.lang.IllegalArgumentException: The AJP Connector is configured with secretRequired="true" but the secret attribute is either null or "". This combination is not valid.
In this case I tried deleting "com.openkm.dao.bean.NodeBase" and "com.openkm.dao.bean.NodeDocumentation" from tomcat/repository/index and it worked perfectly, but I can't understand what is causing this issue, do I need to follow this process every time this happens and also this happen anytime like an hour ago it worked fine but after some time after stooping it, it cause this issue so is there any permanent solution for this.
