I am working on an application that extracts objects based on their ID from a NoSQL CosmosDB. The container has the following details:

• ContainerName: ScenariosTable
• Partition key: /_partitionKey
• Type: Non-hierarchical

Here are the relevant methods:

[HttpGet("GetScenario/{scenarioId}")]
public async Task<string> GetScenarioAsync(string scenarioId, [FromQuery] string version = "")
{
    Scenario result;
    if (string.IsNullOrEmpty(version) || string.Equals(version, "undefined"))
    {
        result = await repository.GetItemByQueryAsync(s => s.Id == scenarioId).ConfigureAwait(false);
    }
    else
    {
        result = await historyRepository.GetItemByQueryAsync(s => s.Id == scenarioId).ConfigureAwait(false);
    }

    if (result != null)
    {
        return JsonConvert.SerializeObject(result);
    }
    else
    {
        throw new ApplicationException($"Could not retrieve scenario definition");
    }
}

public async Task<T> GetItemByQueryAsync(Expression<Func<T, bool>> predicate)
{
    var result = await GetDocumentsCollectionAsync(predicate).ConfigureAwait(false);
    return result.FirstOrDefault();
}

private async Task<IEnumerable<T>> GetDocumentsCollectionAsync(Expression<Func<T, bool>> predicate)
{
    IDocumentQuery<T> query = client.CreateDocumentQuery<T>(
        this.documentCollectionUri,
        new FeedOptions { MaxItemCount = -1, EnableCrossPartitionQuery = true, PartitionKey = new PartitionKey("_partitionKey") })
        .Where(predicate)
        .AsDocumentQuery();

    List<T> results = new List<T>();
    while (query.HasMoreResults)
    {
        results.AddRange(await query.ExecuteNextAsync<T>().ConfigureAwait(false));
    }

    return results;
}

this is the error:
Microsoft.Azure.Documents.DocumentClientException: Cross partition query is required but disabled. Please set x-ms-documentdb-query-enablecrosspartition to true, specify x-ms-documentdb-partitionkey, or revise your query to avoid this exception.

I tried to set in FeedOptions the parameter “EnableCrossPartition” to true but it is still not working
