使用 arangoDB .net 客户端查询时如何避免错误 17？

Question

我查询时一直收到 "expecting non-zero value for . ErrorNumber: 17 HttpStatusCode: 400"。我已尝试尽可能接近 the example 实施它：

示例：

    [Test]
    public void CanQueryDB()
    {
        using (var db = new ArangoDatabase("http://localhost:8529", database: "test"))
        {
            var exDb = db.ListDatabases();
            if (exDb.Contains("test"))
            {
                db.DropDatabase("test");
            }
            db.CreateDatabase("test");


            var obj = new SomeClass() {Key = "1", Text = "Heyheyhey!"};
            _db.Insert<RelevanceContext>(obj);
            Assert.That(() =>

                //How else would you do it?
                _db.Query<RelevanceContext>().Where(x => true).ToArray()

                , Throws.Nothing);
        }
    }

    public class SomeClass
    {
        [DocumentProperty(Identifier = IdentifierType.Key)]
        public string Key;
        public string Text;
    }

结果：

我正在使用 ArangoDB.Client v. 0.7.2.1（nuget.org 上的最新稳定版本）和运行 AngoroDB-2.7.0 (win64)。我也试过 v. 2.6.9，但还是一样。

我可以毫无问题地插入和更新
