調査

以下のコマンドを実行してログを閲覧した．

kubectl logs carts-78d7c69cb8-cp9xd

その結果，ログの中に以下を見つけた．

2022-11-25 08:47:35.576 ERROR [carts,,,] 7 --- [p-nio-80-exec-2] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.mongodb.UncategorizedMongoDbException: Query failed with error code 352 and error message 'Unsupported OP_QUERY command: find.

特に以下の部分がヒントになる．

nested exception is com.mongodb.MongoQueryException: Query failed with error code 352 and error message 'Unsupported OP_QUERY command: find. The client driver may require an upgrade.
