java - java.io.IOException を修正する方法: 閉じたストリームからの読み取りを試みましたか?

Question

2 番目の print ステートメントで IO エラーをスローする以下のコードがあります。なぜ投げているのかわかりません。誰でも私を助けることができますか？その行にコメントすると、正常に機能します。私が理解したのは、応答オブジェクトを 2 回使用していますが、複数回使用できるはずです。

Response response=customerResource.customerOperations("post",
    MDFCommonUtil.getInstance()
    .readFileAsString("CommonFiles/payloadForPost.xml"),null);

System.out.println("inside the methid=="+response.getStatusCode());
    
System.out.println("inside the methid=="+response.asString());
