I have recently upgraded from HYbris 6.3 to HYbris 1811 version. I see the below issue while performing platform update: INFO [hybrisHTTP40] [Initialization] ################ Storing Generic Audit Report configurations ... ERROR [hybrisHTTP40] [HacInitUpdateFacade] Failed to initialize de.hybris.platform.servicelayer.exceptions.ModelSavingException: [de.hybris.platform.validation.interceptors.ValidationInterceptor@441d3404]: unexpected validator error: null at de.hybris.platform.servicelayer.internal.model.impl.wrapper.ModelWrapper.invokeValidateInterceptors(ModelWrapper.java:315) ~[coreserver.jar:?] at de.hybris.platform.servicelayer.internal.model.impl.wrapper.ModelWrapper.validate(ModelWrapper.java:239) ~[coreserver.jar:?] at de.hybris.platform.servicelayer.internal.model.extractor.impl.DefaultModelExtractor.process(DefaultModelExtractor.java:57) ~[coreserver.jar:?] at de.hybris.platform.servicelayer.internal.model.impl.DefaultModelService.performPersistenceOperations(DefaultModelService.java:710) ~[coreserver.jar:?] at de.hybris.platform.servicelayer.internal.model.impl.DefaultModelService.saveAllInternal(DefaultModelService.java:705) ~[coreserver.jar:?] at de.hybris.platform.servicelayer.internal.model.impl.DefaultModelService.saveAll(DefaultModelService.java:685) ~[coreserver.jar:?] at de.hybris.platform.servicelayer.internal.model.impl.DefaultModelService.save(DefaultModelService.java:633) ~[coreserver.jar:?] at de.hybris.platform.audit.internal.config.DefaultAuditConfigService.storeConfiguration(DefaultAuditConfigService.java:136) ~[coreserver.jar:?] at de.hybris.platform.audit.internal.config.DefaultAuditConfigService.storeConfiguration(DefaultAuditConfigService.java:124) ~[coreserver.jar:?] My server is not starting up post this.
