"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.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.

### Configuration

_No response_

### Other information

_No response_

Comece pelo desserializador gerado de EdiscoveryEstimateOperation em EdiscoveryEstimateOperation.java:41 e rastreie JsonParseNode.getEnumSetValue, usando a reported lastEstimateStatisticsOperation request como reprodução. Compare o tratamento da resposta para statisticsOptions com a API response e adicione ou atualize um teste de desserialização focado se o repositório fornecer um. Está concluído quando a chamada retornar um EdiscoveryEstimateOperation sem a exceção de coleção vazia.
