elasticsearch 尝试索引文档时出现错误：“引用”；在序列化设置中只允许值列表“；

尝试为以下文档编制索引时：

我得到以下错误：

{"error":{"root_cause":[{"type":"settings_exception","reason":"Failed to load settings from [{\"interfaces\":[],\"imports\":[{\"name\":\"java.io.BufferedReader\",\"wildcard\":false},{\"name\":\"java.io.InputStreamReader\",\"wildcard\":false}],\"package\":\"\",\"methods\":[{\"parent\":\"removeDuplicateFromString\",\"line_count\":9,\"line\":11,\"documentation\":\"\",\"name\":\"main\",\"cyclomatic_complexity\":1,\"modifiers\":[\"public\",\"static\"],\"params\":[{\"name\":\"args\",\"type\":\"String[]\"}],\"type_\":\"void\",\"generic\":\"\"},{\"parent\":\"removeDuplicateFromString\",\"line_count\":16,\"line\":29,\"documentation\":\"\",\"name\":\"removeDuplicate\",\"cyclomatic_complexity\":5,\"modifiers\":[\"public\",\"static\"],\"params\":[{\"name\":\"s\",\"type\":\"String\"}],\"type_\":\"String\",\"generic\":\"\"}],\"number_forks\":1695,\"classes\":[{\"implements\":[],\"line_count\":36,\"extends\":[],\"line\":10,\"documentation\":\"\",\"name\":\"removeDuplicateFromString\",\"content_count\":2,\"modifiers\":[\"public\"],\"generic\":\"\"}],\"repository\":\"TheAlgorithms/Java\",\"branch\":\"master\",\"commit_hash\":\"e53249ba2381d2f20f3d4493ad70e2da0abb3b05\",\"enums\":[],\"path\":\"Others\",\"license\":\"\",\"filename\":\"removeDuplicateFromString.java\",\"number_watchs\":394,\"contributors\":[{\"name\":\"varunu28\",\"id\":\"7676016\",\"url\":\"https://github.com/varunu28\"}],\"fields\":[],\"number_stars\":4000}]"}],"type":"settings_exception","reason":"Failed to load settings from [{\"interfaces\":[],\"imports\":[{\"name\":\"java.io.BufferedReader\",\"wildcard\":false},{\"name\":\"java.io.InputStreamReader\",\"wildcard\":false}],\"package\":\"\",\"methods\":[{\"parent\":\"removeDuplicateFromString\",\"line_count\":9,\"line\":11,\"documentation\":\"\",\"name\":\"main\",\"cyclomatic_complexity\":1,\"modifiers\":[\"public\",\"static\"],\"params\":[{\"name\":\"args\",\"type\":\"String[]\"}],\"type_\":\"void\",\"generic\":\"\"},{\"parent\":\"removeDuplicateFromString\",\"line_count\":16,\"line\":29,\"documentation\":\"\",\"name\":\"removeDuplicate\",\"cyclomatic_complexity\":5,\"modifiers\":[\"public\",\"static\"],\"params\":[{\"name\":\"s\",\"type\":\"String\"}],\"type_\":\"String\",\"generic\":\"\"}],\"number_forks\":1695,\"classes\":[{\"implements\":[],\"line_count\":36,\"extends\":[],\"line\":10,\"documentation\":\"\",\"name\":\"removeDuplicateFromString\",\"content_count\":2,\"modifiers\":[\"public\"],\"generic\":\"\"}],\"repository\":\"TheAlgorithms/Java\",\"branch\":\"master\",\"commit_hash\":\"e53249ba2381d2f20f3d4493ad70e2da0abb3b05\",\"enums\":[],\"path\":\"Others\",\"license\":\"\",\"filename\":\"removeDuplicateFromString.java\",\"number_watchs\":394,\"contributors\":[{\"name\":\"varunu28\",\"id\":\"7676016\",\"url\":\"https://github.com/varunu28\"}],\"fields\":[],\"number_stars\":4000}]","caused_by":{"type":"illegal_state_exception","reason":"only value lists are allowed in serialized settings"}},"status":500}

据我所知，主要问题要么在部分中描述为：

{"type":"illegal_state_exception","reason":"only value lists are allowed in serialized settings"}}

或：

但是我找不到关于这个错误的任何信息，也找不到它可能是由什么引起的。我尝试了使用带有映射的预定义索引和不存在的索引建立索引。似乎什么都不管用

为什么我不能为这个文档编制索引？

事实证明，正如Farid在评论部分中提到的，我在从命令行编制索引时使用了错误的命令

要运行的正确命令是

curl -X POST -H 'Content-Type: application/json' [index location] -d [data]

---

这里的关键是使用POST而不是PUT，这就是我所做的。

为使用Kibana开发工具的用户添加此功能。 关键是在添加文档时，在索引名后使用文档类型

POST /{index name}/{document type}
{
   request body (document) goes here.
}

---

您正在运行什么命令来索引该文档？我能够使用

POST-foo/\u-doc

成功地为它编制索引。将文档作为主体运行

PUT foo

，会给我带来错误，这是有道理的，因为它试图创建映射，但语法错误。

POST /{index name}/{document type}
{
   request body (document) goes here.
}
