C# MVC can't Deserialize a tuple

I have a Json model that looks like this

private class SearchMetadataJson  {        public string entertain { get; set; }        public string master { get; set; }        public string memail { get; set; }        public string key { get; set; }        public (int, string)[] mood { get; set; }        public int? soundnumber { get; set; }        public int? ftv { get; set; }        public int? com { get; set; }        public (int, string)[] sims { get; set; }        public (int, string)[] keysecond { get; set; }        public string popt { get; set; }        public (string, string) syncs { get; set; }   }  

And I try to de-serialize the object like this

var CommentObj = JsonSerializer.Deserialize<SearchMetadataJson>(CommentAsString);  

The data that I'm trying to de-serialize (aka "CommentAsString") looks like this

"{\"entertain\":\"PEG\",\"master\":\"Phos Ent Group\",\"memail\":\"example@example.com\",\"key\":\"Db\",\"mood\":{\"1\":\"TypeA\",\"4\":\"TypeB\",\"5\":\"TypeC\"},\"soundnumber\":\"5\",\"ftv\":\"4\",\"com\":\"3\",\"sims\":{\"1\":\"Band1\",\"2\":\"Band2\"},\"keysecond\":{\"1\":\"KeyWord1\",\"2\":\"KeyWord2\",\"3\":\"KeyWord3\"},\"syncs\":{\"Other pubber\":\"example2@example.com\"}}"  

But I keep getting this error

Does anyone see what the problem is?
