WSO2 - ESB経由でのプロキシのポストリクエストの失敗

皆さん、私のWSO2 - ESBの問題でお手伝いできますか？WSO2 - ESB経由でのプロキシのポストリクエストの失敗

私のUAT環境では次のエラーが発生していますが、私のSIT環境では発生していません。なぜ私はCARファイルを変更したり、必要に応じて適切な設定をサーバに追加することができるのかというヒントが必要です。

クライアントがPost要求を行っているときに、タイムアウトエラーが発生しています。ログをチェックすると、ペイロードがJSONとして書き込めないというエラーが表示されます。これはGETリクエストでは起こりませんので、私は迷っています。また、リクエストがGET/POSTを使ってバックエンドで送信されていることを確認することもできます。

次のサーバは存在しないので、app03/app04というサーバに接続できないことに注意してください（私たちは2つのUATサーバを持っていますが、PRD環境では4つしかありません）。

私が理解できないのは、これがPost要求でのみ発生し、コードを変更したり、WSO2-ESBサーバーで何かを設定しなければならない理由です。

説明や追加情報については、お気軽にお問い合わせください。あなたの助け

'targetURL'の使用が正しくありません。代わりにそう<send>でエンドポイントを定義

<send> 
    <endpoint key="XXXX-ws_LBEP" />
