We have run into a scenario where one of the fields in our couchbase documents has a "long" (0) instead of the string ("0"). We are using dynamic mapping. There are conflicting data types for this field "doc.gameJournalEntries.gameAction.gameType" In most cases, values for this field is a string. However, a few documents now have a long value of 0. This is throwing the dynamic mapper of ElasticSearch into an exception and data stops replicating from Couchbase. Technically, ES should be able to handle this and I tried adding dynamic templates to handle this, but ES seems to be picky, in that, once dynamic mapping identifies a field data type, it expects all data for that field to be in the same data type. Here is the couchbase\_template.json ``` { "template" : "*", "order" : 10, "mappings" : { "couchbaseCheckpoint" : { "_source" : { "includes" : ["doc.*"] }, "dynamic_templates": [ { "longs": { "match_mapping_type": "long", "mapping": { "type": "text" } } }, { "strings": { "match_mapping_type": "string", "mapping": { "type": "text" } } }, { "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 } } } } ``` } And here is the exception: ``` [2018-01-05T23:34:20,083][ERROR][o.e.t.c.c.CouchbaseCAPITransportImpl] [wKd0fSJ] Error indexing document, will NOT retry.

I also tried adding a dynamic rule: `{ "type_as_strings": { "match": "[doc.gameJournalEntries.gameAction.gameType]", "mapping": { "type": "text" } } },` This did not help ---
