Hi, We are trying to execute a report using visualize.js library. Although the report got executed successfully, the server threw an error to the client "resource.not.found : Resource 70779358-c03b-40d5-a37c-79b42ac47964 not found". We see below error in the Server Logs. It would be great if anyone can throw some light on this. P.S: The same report works fine when accessed via JasperReport UI. 2019-05-15 06:39:18,879 DEBUG EngineServiceImpl,pool-6-thread-6:755 - Report fill error com.jaspersoft.jasperserver.api.JSException: Exception getting data strategyorg.springframework.security.core.authority.SimpleGrantedAuthority cannot be cast to com.jaspersoft.jasperserver.api.metadata.user.domain.Role Arguments: at com.jaspersoft.ji.adhoc.datasource.AdhocDataSourceService.setReportParameterValues(AdhocDataSourceService.java:196) at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.EngineServiceImpl.fillReport(EngineServiceImpl.java:1806) at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.EngineServiceImpl$ReportFill.runWithDataSource(EngineServiceImpl.java:1143) at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.EngineServiceImpl$ReportFill.runReport(EngineServiceImpl.java:1072) at com.jaspersoft.jasperserver.api.engine.jasperreports.service.impl.EngineServiceImpl$ReportRunnable.run(EngineServiceImpl.java:967) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.ClassCastException: org.springframework.security.core.authority.SimpleGrantedAuthority cannot be cast to com.jaspersoft.jasperserver.api.metadata.user.domain.Role at com.jaspersoft.commons.datarator.DefaultCacheKeyInterceptor$UserImplThatComparesRoles.<init>(DefaultCacheKeyInterceptor.java:126) at com.jaspersoft.commons.datarator.DefaultCacheKeyInterceptor.getCacheKeyCalled(DefaultCacheKeyInterceptor.java:98) at com.jaspersoft.commons.datarator.CachedDatasetKey.<init>(CachedDatasetKey.java:226) at com.jaspersoft.commons.datarator.BaseDataSetCacheImpl.getCachedDataSet(BaseDataSetCacheImpl.java:113) at com.jaspersoft.commons.datarator.BaseDataSetCacheImpl.getWorkingDataSet(BaseDataSetCacheImpl.java:280) at com.jaspersoft.commons.semantic.dsimpl.memory.MemoryDataSet.getWorkingDataSet(MemoryDataSet.java:103) at com.jaspersoft.commons.semantic.dsimpl.memory.MemoryDataSet.getWorkingDataSet(MemoryDataSet.java:76) at com.jaspersoft.ji.adhoc.strategy.CommonDomainDataStrategy.getWorkingDataSet(CommonDomainDataStrategy.java:1358) at com.jaspersoft.ji.adhoc.strategy.CommonDomainDataStrategy.getRuntimeDataSet(CommonDomainDataStrategy.java:1770) at com.jaspersoft.ji.adhoc.strategy.DomainDataStrategy.getRuntimeDataSet(DomainDataStrategy.java:323) at com.jaspersoft.ji.adhoc.strategy.CompiledDomainQuery.getRuntimeDataSet(CompiledDomainQuery.java:103) at com.jaspersoft.ji.adhoc.datasource.AdhocDataSourceService.setReportParameterValues(AdhocDataSourceService.java:167) ... 7 more Thanks Pranesh
