如何修复[description]的此错误映射器与现有映射器冲突:无法将参数[分析器]从[my_analyzer]更新为[default]

from elasticsearch import Elasticsearch

es = Elasticsearch()

# 定义新的映射
new_mapping = {
    "mappings": {
        "properties": {
            "[分析器]": {
                "type": "text",
                "analyzer": "default"
            }
        }
    }
}

# 创建新索引
es.indices.create(index="new_index", body=new_mapping)

# 重新索引数据
es.reindex(body={
    "source": {"index": "old_index"},
    "dest": {"index": "new_index"}
})

# 创建新索引并设置映射
es.indices.create(index="new_index", body=new_mapping)

# 更新别名
es.indices.update_aliases(body={
    "actions": [
        {"remove": {"index": "old_index", "alias": "my_alias"}},
        {"add": {"index": "new_index", "alias": "my_alias"}}
    ]
})

dynamic_mapping = {
    "mappings": {
        "dynamic_templates": [
            {
                "strings_as_keywords": {
                    "match_mapping_type": "string",
                    "mapping": {
                        "type": "keyword"
                    }
                }
            }
        ]
    }
}

es.indices.create(index="new_index", body=dynamic_mapping)
