Hello ES experts, We are running into an issue with certain documents that are ingested in by transport-couchbase. The doc is and error is listed below. Any ideas `[{ "poc": { "cas": 1511944677515919400, "docType": "Game", "docVersion": "1.0", "gameId": "4d77c7a3-c3d6-4b59-9283-08add213420d", "gameState": { "jackpot": 0, "some3History": [ null], "some5History": [null] }, "gameType": "SomeGame", "guests": [], "index": 0, "isActive": true, "parentId": null, "serverFullName": null, "updateTimestamp": "2017-11-29T08:37:57.565371+00:00" } } ]` the error is: ```auto [2018-01-15T17:06:17,340][ERROR][o.e.t.c.c.CouchbaseCAPITransportImpl] [kYdTvkJ] bulk index requestId=42898 Failing due to errors: MapperParsingException[failed to parse [doc.gameState]]; nested: IllegalStateException[Can't get text on a START_OBJECT at 1:360]; [2018-01-15T17:06:17,340][WARN][o.e.j.s.ServletHandler] /poc-sandbox%2f423/_bulk_docs java.lang.RuntimeException: MapperParsingException[failed to parse [doc.gameState]]; nested: IllegalStateException[Can't get text on a START_OBJECT at 1:360]; at org.elasticsearch.transport.couchbase.capi.ElasticSearchCAPIBehavior.bulkDocs(ElasticSearchCAPIBehavior.java:548) ~[elasticsearch-transport-couchbase-3.0.0-cypress-es5.6.4-all.jar:?] at com.couchbase.capi.servlet.CAPIServlet.handleBulkDocs(CAPIServlet.java:532) ~[couchbase-capi-server-1.6.3.jar:?] at com.couchbase.capi.servlet.CAPIServlet.service(CAPIServlet.java:89) ~[couchbase-capi-server-1.6.3.jar:?] at javax.servlet.http.HttpServlet.service(HttpServlet.java:790) ~[javax.servlet-api-3.1.0.jar:3.1.0] at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:845) ~[jetty-servlet-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:584) [jetty-servlet-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) [jetty-server-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:513) [jetty-security-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:226) [jetty-server-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1180) [jetty-server-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:512) [jetty-servlet-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185) [jetty-server-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1112) [jetty-server-9.3.13.v20161014.jar:9.3.13.v20161014] at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) [jetty-server-9.3.13.v20161014.jar:9.3. ``` ---

Pretty sure that your mapping says that gamestate is a text field and here you try to put an object for that field. Check your mapping. ---

Thanks David! I actually do not have have any mapping for gameState. Here is my mapping: ```auto "template" : "*", "order" : 10, "mappings" : { "couchbaseCheckpoint" : { "_source" : { "includes" : ["doc.*"] }, "dynamic_templates": [ { "longs_as_strings": { "match": "[doc.id]", "mapping": { "type": "text" } } }, { "longs_as_floats": { "match": "[doc.bridgeServerBalanceAmount]", "mapping": { "type": "float" } } }, { "store_no_index": { "match": "*", "mapping": { "store" : "no", "index" : "no", "include_in_all" : false } } } ] }, "doc": { "properties": { "id": { "type": "text" } , "doc.id": { "type": "text" } } }, "_default_" : { "_source" : { "includes" : ["meta.*","doc.*"] }, "properties" : { "meta" : { "type" : "object", "include_in_all" : false } } } } } ``` ---

This is a template not the actual mapping. ---

Thanks David! I use the DefaultTypeSelector for the mapping - [https://github.com/couchbaselabs/elasticsearch-transport-couchbase/releases/tag/2.1.1-RC](https://github.com/couchbaselabs/elasticsearch-transport-couchbase/releases/tag/2.1.1-RC). For gameState why would it be an issue? ---

I don't know. But what is the current mapping? ```auto GET poc-sandbox%2f423/_mapping ``` ---

Thanks David, you are right. The mapping says it is a text. Since this was auto-generated, - how do I override the auto-generated mapping just for one of the properties, in this case, gameState? - And what is there is at least one document that has gameState a string while others are an object? How do I handle hybrid types especially string / object? Thanks again ---

> how do I override the auto-generated mapping just for one of the properties, in this case, gameState? If you provide a template with this field, it will applied. If this field does not exist, auto-generated mapping for this field will be applied. > How do I handle hybrid types especially string / object? You can't. You need to fix the problem before indexing in elasticsearch. ---
