I'm facing the exact same error with the function CallCloudCodeFunctionAsync
Xamarin Forms shared project too.

I recently encountered this same issue. The problem and the solution is referenced in other issues here, such as #344. Namely, you have to follow the procedure in the README for the Unity client: https://github.com/parse-community/Parse-SDK-dotNET#use-in-unity-client

You have to adapt it a bit for Xamarin. Here is what I've used to get it working with Xamarin Forms 5:

var client = new ParseClient(new ServerConnectionData
            {
                ApplicationID = "...",
                Key = "...",
                ServerURI = "..."
            },
            new LateInitializedMutableServiceHub(),
            new MetadataMutator
            {
                EnvironmentData = new EnvironmentData { OSVersion = Environment.OSVersion.ToString(), Platform = Device.RuntimePlatform, TimeZone = TimeZoneInfo.Local.StandardName },
                HostManifestData = new HostManifestData {
                    Version = this.GetType().Assembly.GetCustomAttribute<AssemblyInformationalVersionAttribute>().InformationalVersion,
                    Name = this.GetType().Assembly.GetName().Name,
                    ShortVersion = this.GetType().Assembly.GetName().Version.ToString(),
                    Identifier = AppDomain.CurrentDomain.FriendlyName
                }
            });
