I am seeing MappingParsingException logged in the elasticsearch log and I find that it is correct. My code has a bug for a field. The issue is that no error was thrown to my RestHighLevelClient. I want my application to be able to at least log that there was an indexing issue. I would prefer indexing of the entire document to fail rather than silently ignoring the erroneous field. I thought maybe I have "ignore\_malformed" set to true, but it doesn't appear to be set on the index. Not sure if it is (can) be set at the global level. Should I just set "ignore\_malformed" to false on each index?

Here are my current settings:

```auto
    "settings" : {
      "index" : {
        "creation_date" : "1593197783182",
        "number_of_shards" : "1",
        "number_of_replicas" : "1",
        "uuid" : "sHNzsNm4Td-FwwR47Yysfw",
        "version" : {
          "created" : "7070099"
        },
        "provided_name" : "dev1_uee_search_requests"
      }
    }

```

I tried setting ignore\_malformed on my existing index but I get

"Can't update non dynamic settings [[index.mapping.ignore\_malformed]] for open indices
