Searchkick::InvalidQueryError（映射错误 - 运行 Record.reindex）

Question

为 Rails 6 应用从 Elasticsearch 迁移到 Opensearch（1.3.1，Mac 自制软件）引起的另一个问题。

Loading test environment (Rails 6.1.4.7)
>> r = Record.find(638205575)
  Record Load (0.4ms)  SELECT "records".* FROM "records" WHERE "records"."id" =  LIMIT   [["id", 638205575], ["LIMIT", 1]]

Traceback (most recent call last):
Searchkick::InvalidQueryError (Bad mapping - run Record.reindex)

我在该输出中看不到任何指示查询无效或映射错误的信息。实际上 运行 Record.reindex 没有显示任何错误，只是在控制台中用 true 响应。

任何人都可以看到任何可能提供线索的东西吗？

这个问题的原因与 and, ultimately, to Searchkick memory leak有关。

用自定义 rake 任务代替 rake searchkick:reindex:all 导致无法正确构建索引。例如，这是两个不同结果的差异（右侧 searchkick 任务的正确索引）：

"records_development" : {                       |   "records_development_20220425162622176" : {
