"unknown parameter [fielddata] on mapper [userName] of type [keyword]"

Open Source Elasticsearch and Kibana
1

After upgrade from opendistro from 1.11.0 to 1.13.2, I got the error message for the existing index - “unknown parameter [fielddata] on mapper [userName] of type [keyword]”.

How to fix?

Do I need to modify the index template for string_fields?

      "dynamic_templates" : [
        {
          "resources_match": {
             "path_match":  "resources.*",
             "mapping" : {
             "fielddata": false,
             "index" : true,
             "norms" : false,
             "type" : "text"
            }
          }
        },
        {
          "string_fields": {
            "mapping": {
              "fielddata": false,
              "index": true,
              "norms": false,
              "type": "keyword",
              "ignore_above": 256
            },
            "match_mapping_type": "string",
            "match": "*"
          }
        }
      ],
