"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_

Inizia dal deserializzatore generato di EdiscoveryEstimateOperation in EdiscoveryEstimateOperation.java:41 e segui JsonParseNode.getEnumSetValue, usando la reported lastEstimateStatisticsOperation request come riproduzione. Confronta la gestione della risposta per statisticsOptions con la API response e aggiungi o aggiorna un test di deserializzazione mirato se il repository ne fornisce uno. Il lavoro è completato quando la chiamata restituisce un EdiscoveryEstimateOperation senza l’eccezione di raccolta vuota.
