I am working with Janusgraph among Kotlin. I just tried to import some data to Janusgraph. But I get this Error.
: Servlet.service() for servlet [dispatcherServlet] in context with path  threw exception [Request processing failed; nested exception is org.janusgraph.core.SchemaViolationException: Adding this property for key [ALIAS] and value [22203-tour1] violates a uniqueness constraint [aliasIndex]] with root cause
Is this trouble from janusgraph. Could you say how I can fix it?
