What happened?

The BiDi type Scipt.LocalValue.Map should be passable to the Script.CallFunctionAsync method. However, it fails with a strange exception.

Per the spec, the Map is serialized the same was an Object is:

An Object is an IEnumerable<IEnumerable<LocalValue>>, and works fine in this scenario. For that reason, I am suspicious if Map should be changed into the same shape.

Same thing applies for the returned RemoteValue.Map.

How can we reproduce the issue?

#
var bidi = await driver.AsBiDiAsync();
var context = (await bidi.BrowsingContext.GetTreeAsync())[0].Context;
var map = new LocalValue.Map(new Dictionary<string, LocalValue>
{
    {"key", new LocalValue.String("value") }
});
var response = await context.Script.CallFunctionAsync($$"""
     (arg) => {
       return arg;
     }
     """, false, new() { Arguments = [map] });
