Hello,  
I started using nexus 3.56.0 and noticed the following error when removing a repository:  
2023-07-04 16:10:28,626+0000 INFO [qtp547721895-567] org.sonatype.nexus.repository.manager.internal.RepositoryManagerImpl - Deleted repository: staging-20230704161027197Z15483504002-results  
2023-07-04 16:10:28,663+0000 ERROR [qtp547721895-567] org.sonatype.nexus.extdirect.internal.ExtDirectExceptionHandler - Failed to invoke action method: coreui\_Repository.remove, java-method: org.sonatype.nexus.coreui.RepositoryComponent.remove  
java.lang.NullPointerException: null

I run nexus the following way:  
docker run   
–name nexus   
–env INSTALL4J\_ADD\_VM\_PARAMS=“-Xms4g -Xmx4g -Djava.util.prefs.userRoot=/opt/sonatype/sonatype-work/nexus/javaprefs”   
-v $nexusDirectory/nexus.properties:/nexus-data/etc/nexus.properties   
-v $nexusDirectory/keystore.jks:/opt/sonatype/nexus/etc/ssl/keystore.jks   
-v /data/nexus-data:/nexus-data   
-d
