我有stargate 1.0.38在我的开发服务器上运行的很好。我可以使用stargate rest api来获得auth_token并运行插入，选择查询。
昨天，我在我的Cassandra DSE 6.8中为一个表创建了一个索引Cql 3SolrSecondaryIndex。然后我在stargate日志中看到了bellow错误。之后，我删除了该索引。但即使删除了该索引，我仍然在stargate日志中看到bellow错误。我也尝试停止/启动stargate，但仍然看到相同的错误。

由于此错误，我仍然能够获取auth_token，但所有选择查询都出现此错误

{
    "description": "Resource not found: keyspace 'test' not found",
    "code": 404
}

请帮助我解决此问题。
