Hello, I have just migrated to elasticsearch 6.0.1 (I was using 5.6.5 before). I have some problem with cat API as when I : ``` GET /_cat/allocation?v GET /_cat/indices?v GET /_cat/nodes ``` I receive this message ``` { "error": { "root_cause": [ { "type": "null_pointer_exception", "reason": null } ], "type": "null_pointer_exception", "reason": null }, "status": 500 } ``` and also in powershell : > ``` > [WARN][r.suppressed] path: /_cat/indices, params: {v=} > java.lang.NullPointerException: null > at org.elasticsearch.common.io.stream.StreamOutput.writeStringList(StreamOutput.java:949) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.cluster.metadata.IndexTemplateMetaData.writeTo(IndexTemplateMetaData.java:248) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.cluster.metadata.MetaData.writeTo(MetaData.java:695) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.cluster.ClusterState.writeTo(ClusterState.java:686) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.discovery.zen.PublishClusterStateAction.serializeFullClusterState(PublishClusterStateAction.java:351) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.admin.cluster.state.TransportClusterStateAction.masterOperation(TransportClusterStateAction.java:136) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.admin.cluster.state.TransportClusterStateAction.masterOperation(TransportClusterStateAction.java:44) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.master.TransportMasterNodeAction.masterOperation(TransportMasterNodeAction.java:87) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.master.TransportMasterNodeAction$AsyncSingleAction$2.doRun(TransportMasterNodeAction.java:166) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.common.util.concurrent.AbstractRunnable.run(AbstractRunnable.java:37) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.common.util.concurrent.EsExecutors$1.execute(EsExecutors.java:139) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.master.TransportMasterNodeAction$AsyncSingleAction.doStart(TransportMasterNodeAction.java:163) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.master.TransportMasterNodeAction$AsyncSingleAction.start(TransportMasterNodeAction.java:126) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.master.TransportMasterNodeAction.doExecute(TransportMasterNodeAction.java:104) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.master.TransportMasterNodeAction.doExecute(TransportMasterNodeAction.java:54) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.TransportAction$RequestFilterChain.proceed(TransportAction.java:167) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.TransportAction.execute(TransportAction.java:139) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.action.support.TransportAction.execute(TransportAction.java:81) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.client.node.NodeClient.executeLocally(NodeClient.java:83) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.client.node.NodeClient.doExecute(NodeClient.java:72) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.client.support.AbstractClient.execute(AbstractClient.java:405) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.client.support.AbstractClient$ClusterAdmin.execute(AbstractClient.java:712) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.client.support.AbstractClient$ClusterAdmin.state(AbstractClient.java:748) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.rest.action.cat.RestIndicesAction.lambda$doCatRequest$0(RestIndicesAction.java:91) ~[elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.rest.BaseRestHandler.handleRequest(BaseRestHandler.java:97) [elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.rest.RestController.dispatchRequest(RestController.java:240) [elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.rest.RestController.tryAllHandlers(RestController.java:336) [elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.rest.RestController.dispatchRequest(RestController.java:174) [elasticsearch-6.0.1.jar:6.0.1] > at org.elasticsearch.http.netty4.Netty4HttpServerTransport.dispatchRequest(Netty4HttpServerTransport.java:491) [transport-netty4-6.0.1.jar:6.0.1] > at org.elasticsearch.http.netty4.Netty4HttpRequestHandler.channelRead0(Netty4HttpRequestHandler.java:80) [transport-netty4-6.0.1.jar:6.0.1] > > ``` However I have a good answer when I ask GET \_cat/recovery for example and index can also be retrieved.
