I want to send a command between two projects in the same context, but i have this error

Servlet.service() for servlet [dispatcherServlet] in context with path threw exception [Request processing failed; nested exception is java.lang.RuntimeException: java.util.concurrent.ExecutionException: org.axonframework.queryhandling.QueryExecutionException: non null hash key required] with root cause
AxonServerRemoteQueryHandlingException{message=An exception was thrown by the remote message handling component: non null hash key required, errorCode=‘AXONIQ-5001’, location=‘dev_context’}
