elasticsearch - 尝试索引文档时出现错误 : "only value lists are allowed in serialized settings"

Question

当尝试索引以下文档时:

{

"classes": [

    }
],

            {
                "name": "s",
                "type": "String"
            }
        ],

我收到以下错误:

{"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，主要问题在以下部分中进行了描述:

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

或者:

"error":{"root_cause":[{"type":"settings_exception","reason":"Failed to load settings from [{\"interfaces\":[],\"imports\": ........

但我找不到有关此错误或其可能原因的任何信息。我尝试过使用带有映射的预定义索引和不存在的索引来建立索引。似乎没有任何作用。

为什么我无法索引该文档？

Answer 1

事实证明，正如 Farid 在评论部分中提到的那样，我在从命令行建立索引时使用了错误的命令。

正确的运行命令是

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

关键是你使用 POST 而不是 PUT，这正是我正在做的。
