java.lang.UnsupportedOperationException using GetSchedulePostResponse

Describe the bug

I have a scheduler that runs every hour that gets schedule for all our users and saves them in the db. But alot of calls (more than 50%) throws weird error. I haven't found anything on google that could fix this error and i am unable to fix it for days now.

Expected behavior

I am using following dependencies:

<dependency>
	<groupId>com.microsoft.azure</groupId>
	<artifactId>msal4j</artifactId>
	<!--<version>1.17.1</version>-->
	<version>1.18.0</version>

This is the error that i get:

I think the error happens at this line of code:

            response = batchResponseContent.getResponseById(responseId, GetSchedulePostResponse::createFromDiscriminatorValue);

从 MicrosoftGraphClient.java 第 223 行开始，以报告的 TextParseNode 异常作为切入点，跟踪 BatchResponseContentCollection.getResponseById 经过 BatchResponseContent 和 ResponseBodyHandler 的调用路径。使用列出的 Graph SDK 版本复现批处理请求，并确定为什么某些响应会被解析为文本；完成的标准是解释清楚该失败原因，并通过适当的回归测试覆盖受影响的响应处理行为。
