(I also think that this feature is useful for other users.)15var foo = new Dictionary<string, object>();16foo["foo"] = foo;17var exception = await PlaywrightAssert.ThrowsAsync<PlaywrightSharpException>(() => Page.EvaluateAsync(@"({foo}) => foo", new { foo }));18StringAssert.Contains("Object is not serializable", exception.Message);19I tried what you suggested, but the test still failed. (I'm sorry if I'm missing something.)20I think the problem is that the Dictionary<string, object> passed to the EvaluateAsync method is converted to JSON, but the Dictionary<string, object> passed to the JavaScript function is not converted to JSON. (I think this is because the Dictionary<string, object> passed to the EvaluateAsync method is converted to JSON using the Json.Net library, but the Dictionary<string, object> passed to the JavaScript function is converted to JSON using the JavaScript engine.)21{22 {
