elasticsearch mapper_parsing_exception Root mapping definition has unsupported parameters

Question

I'm having the following issue with elasticsearch 7 when trying creating a template.

When I'm trying to copy template from elasticsearch 6 to 7 and some of the fields I have removed as per the elasticsearch 7 .e

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "Root mapping definition has unsupported parameters:  [events : {properties={msg={fields={raw={type=keyword}}}, requestId={type=keyword}, logger={type=keyword}, host={type=keyword}, jwtOwner={type=keyword}, requestOriginator={type=keyword}, tag={analyzer=firsttoken, fields={disambiguator={analyzer=keyword, type=text}}}, jwtAuthenticatedUser={type=keyword}, thread={type=keyword}, requestChainOriginator={type=keyword}, revision={type=keyword}}}]"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:  [events : {properties={msg={fields={raw={type=keyword}}}, requestId={type=keyword}, logger={type=keyword}, host={type=keyword}, jwtOwner={type=keyword}, requestOriginator={type=keyword}, tag={analyzer=firsttoken, fields={disambiguator={analyzer=keyword, type=text}}}, jwtAuthenticatedUser={type=keyword}, thread={type=keyword}, requestChainOriginator={type=keyword}, revision={type=keyword}}}]",

    }
  },

Please help me resolve the issue. Thanks in advance.

Sorry, Vol and Opster I missed adding events template. I deleted the event because it is not accepting. The following is the template for events.

PUT  _template/logstash
{
    "order" : 0,
    "index_patterns" : [
      "logstash*"
    ],
    "settings" : {
      "index" : {
        "analysis" : {
          "filter" : {
            "firsttoken" : {
              "type" : "pattern_capture",
              "preserve_original" : "false",
              "patterns" : [
                """^([^\.]*)\.?.*$"""
              ]
            },
            "secondtoken" : {
              "type" : "pattern_capture",
              "preserve_original" : "false",
              "patterns" : [
                """^[^\.]*\.([^\.]*)\.?.*$"""
              ]
            },
            "thirdtoken" : {
              "type" : "pattern_capture",
              "preserve_original" : "false",
              "patterns" : [
                """^[^\.]*\.[^\.]*\.([^\.]*)\.?.*$"""

There are two issues. One issue is the one mentioned by @OpsterESNinjaKamal

But it still won't work as the tag field has no type.

Here is the template that will work:

PUT _template/logstash
{
  "order": 0,
  "index_patterns": [
    "logstash*"
  ],
  "settings": {
    "index": {
      "analysis": {
        "filter": {
          "firsttoken": {
            "type": "pattern_capture",
            "preserve_original": "false",
            "patterns": [
              "^([^\\.]*)\\.?.*$"
            ]
          },
          "secondtoken": {
            "type": "pattern_capture",
            "preserve_original": "false",
            "patterns": [
              "^[^\\.]*\\.([^\\.]*)\\.?.*$"
            ]
          },
          "thirdtoken": {
            "type": "pattern_capture",
            "preserve_original": "false",
            "patterns": [
              "^[^\\.]*\\.[^\\.]*\\.([^\\.]*)\\.?.*$"
            ]
          }
        },

          },

            "tokenizer": "keyword"
          }
        }
      },
      "mapper": {}
    }
  },
  "mappings": {

        "type": "text",
        "fields": {
          "raw": {

          }
        }
      },
      "requestId": {

Notice your mappings. ES post version 7.0, doesn't support type i.e. events in this case and that is has been deprecated.

Post version 7.0, you would need to create a separate index for every type you've had in the index prior to version 7.0.

This link should help you as how you can migrate from version 6.x to 7.x

Basically your mappings section would be as follows:

{
   "mappings":{
      "properties":{                     <---- Notice there is no `events` before `properties` as mentioned in your question
         "msg":{
            "type":"text",
            "fields":{
               "raw":{
                  "type":"keyword"
               }
            }
         },
         "requestId":{
            "type":"keyword"
         },
         "logger":{
            "type":"keyword"
         },
         "host":{
            "type":"keyword"
         },
         "jwtOwner":{
            "type":"keyword"
         },
         "requestOriginator":{
            "type":"keyword"
         },
         "tag":{
            "analyzer":"firsttoken",
            "fields":{
               "disambiguator":{
                  "analyzer":"keyword",
                  "type":"text"
               }
            }
         },
         "jwtAuthenticatedUser":{
            "type":"keyword"
         },
         "thread":{
            "type":"keyword"
         },
         "requestChainOriginator":{
            "type":"keyword"
         },
         "revision":{
            "type":"keyword"
         }
      }
   }
