summary: " 版本： 6.8-7.15
 简要来说，当 Elasticsearch 无法将字段解析为地址列表时会出现此错误，原因是字段的格式不正确。该字段必须是字符串或字符串数组。要解决此问题，您应该检查导致错误的字段的格式。确保它是单个字符串或字符串数组。如果不是，您需要将其转换为正确的格式，然后 Elasticsearch 才能解析它。
日志上下文 #   日志“could not parse [” + field + “] as address list. field must either be a string”的类名是 Email.java。 我们从 Elasticsearch 源代码中提取了以下内容，供寻求深入上下文的人使用：
while ((token = parser.nextToken()) != XContentParser.Token.END_ARRAY) { addresses.add(Address.parse(field, token, parser)); } return new Email.AddressList(addresses); } throw new ElasticsearchParseException("could not parse [" + field + "] as address list. field must either be a string " + "(comma-separated list of RFC822 encoded addresses) or an array of objects representing addresses"); } @Override public boolean equals(Object o) { "

## 日志上下文
-----------

日志“could not parse [” + field + “] as address list. field must either be a string”的类名是 [Email.java。](https://www.geeksforgeeks.org/java-lang-class-class-java-set-1/) 我们从 Elasticsearch 源代码中提取了以下内容，供寻求深入上下文的人使用：

```java
    while ((token = parser.nextToken()) != XContentParser.Token.END_ARRAY) {
        addresses.add(Address.parse(field, token, parser));
    }
    return new Email.AddressList(addresses);
    }
    throw new ElasticsearchParseException("could not parse [" + field + "] as address list. field must either be a string " +
        "(comma-separated list of RFC822 encoded addresses) or an array of objects representing addresses");
    }  @Override
    public boolean equals(Object o) {
