"java.lang.IllegalArgumentException: Collection is empty" when calling `lastEstimateStatisticsOperation`

Describe the bug

I'm fetching Search estimate statistics in Purview using the following call:

EdiscoveryEstimateOperation estimateOperation = client.security()
                .cases()
                .ediscoveryCases()
                .byEdiscoveryCaseId(caseId)
                .searches()
                .byEdiscoverySearchId(searchId)
                .lastEstimateStatisticsOperation()
                .get();

This consistently fails with the following error:

java.lang.IllegalArgumentException: Collection is empty
    at java.base/java.util.EnumSet.copyOf(EnumSet.java:177)
    at com.microsoft.kiota.serialization.JsonParseNode.getEnumSetValue(JsonParseNode.java:257)
    at com.microsoft.graph.beta.models.security.EdiscoveryEstimateOperation.lambda$getFieldDeserializers$6(EdiscoveryEstimateOperation.java:41)
    at com.microsoft.kiota.serialization.JsonParseNode.assignFieldValues(JsonParseNode.java:280)

    at com.microsoft.graph.beta.security.cases.ediscoverycases.item.searches.item.lastestimatestatisticsoperation.LastEstimateStatisticsOperationRequestBuilder.get(LastEstimateStatisticsOperationRequestBuilder.java:47)

It seems like response deserialization isn't working correctly, probably for the statisticsOptions field? It might be relevant that there doesn't seem to be any way to specify statisticsOptions when triggering statistics generation through the API.

Expected behavior

I expect this SDK call to successfully return an EdiscoveryEstimateOperation for the given search.

How to reproduce

I'm starting statistics generation with the following call:

client.security()
                .cases()
                .ediscoveryCases()
                .byEdiscoveryCaseId(caseId)
                .searches()
                .byEdiscoverySearchId(searchId)
                .microsoftGraphSecurityEstimateStatistics()
                .post();

Fetching statistics with the call listed above then triggers the bug.

从 EdiscoveryEstimateOperation.java:41 中生成的 EdiscoveryEstimateOperation 反序列化器开始，跟踪 JsonParseNode.getEnumSetValue，并使用报告的 lastEstimateStatisticsOperation request 进行复现。将 statisticsOptions 的响应处理与 API response 进行比较；如果 repository 提供了相关测试，则添加或更新一个针对性的反序列化测试。完成的标准是调用返回 EdiscoveryEstimateOperation，且不会出现空集合异常。
