Attempt to index document gives error: "only value lists are allowed in serialized settings"

I get the following error:

{"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}

From which I've gathered that the main issues are either described in the part saying that: 

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

Or:

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

But I cannot find any information about this error or what it could be caused by. I've tried indexing both using a predefined index with mappings and to a non-existing index. Nothing seems to work.

Why can't I index this document?

Solution

  • It turns out that, as Farid mentioned in the comments section, I was using the wrong command when indexing from the command line.

    The correct command to run is

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

    Where the key is that you use POST and not PUT which is what I was doing.
