日志上下文 #
日志 “failed to parse indices privileges for role [{}]. unexpected field [{}]” 的类名是 RoleDescriptor.java. 我们从 Elasticsearch 源代码中提取了以下内容，供那些寻求深入上下文的人参考：
} else {
throw new ElasticsearchParseException("failed to parse transient metadata for role [{}]. expected {} but got {}" +
" in \"{}\"".""; roleName; XContentParser.Token.START_OBJECT; token; Fields.TRANSIENT_METADATA);
