Error in custom analyzer and mappings in ES v7

Elastic Stack Elasticsearch
1

Hi, I'm trying to migrate my ES setup from 2.3 to 7.5. However, I'm facing an error with my custom analyzer:

elastic: Error 400 (Bad Request): analyzer [keyword_lowercase_remove_space] not found for field [identity_exact] [type=mapper_parsing_exception]

My mappings and analyzer settings look like this:

{
  "settings": {
    "analysis": {
      "analyzer": {
        "keyword_lowercase_remove_space": {
            "type":  "custom",
	        "tokenizer": "keyword",
	        "filter":    []string{"lowercase", "keyword_repeat", "minimal_eng_stem", "custom_unique", "filter_whitespace_remove"}
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "promotions": {
        "properties": {
          "product_name": {
            "type": "text",
            "fields": {
              "identity_exact": {
                "type": "text",
                "analyzer": "keyword_lowercase_remove_space"
              }
            }
          }
        }
      }
    }
  }
}

I'm not able to debug the problem, why this problem is occurring. I've gone through the breaking change documentation but didn't found any relevant solution. It would be great if anyone can help me through this.

I don't have the same message:

            "keyword_repeat",

            "custom_unique",
            "filter_whitespace_remove"
          ]
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "promotions": {
        "properties": {
          "product_name": {
            "type": "text",
            "fields": {
              "identity_exact": {
                "type": "text",
                "analyzer": "keyword_lowercase_remove_space"
              }
            }
          }
        }
      }
    }
  }
}

I'm getting:

{
  "error": {
    "root_cause": [
      {
        "type": "remote_transport_exception",
        "reason": "[instance-0000000020][172.17.0.43:19461][indices:admin/create]"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "Custom Analyzer [keyword_lowercase_remove_space] failed to find filter under name [minimal_eng_stem]"
  },
  "status": 400
}

Which is expected as minimal_eng_stem is not defined.

                "type": "text",
                "analyzer": "keyword_lowercase_remove_space"
              }
            }
          }
        }
      }
    }
  }
}

I've updated this query. This query is giving me same error when I try to create index using NewIndicesCreateService in Golang ES client API and call NewIndicesPutMappingService to put mappings.

When I run it from the Kibana dev console, it works fine.
So I'm guessing there's something wrong with your code or with the Golang ES client you are using.
