[Solved] ASP.NET Core 10 Razor Pages: how to use ObjectDatasource where data source is a method returning a ValueTuple

[Nitin]

I have a class representing a SQL Server stored procedure output. The SP returns two datasets. I have a C# method that takes in parameters and runs the SP. It returns a ValueTuple (2 Lists - 1 each for the SP returned dataset). I tried to assign this method as the data source to an ObjectDatasource in the report (using standalone Report Designer); however I get an unexpected error (screenshot attached). Probably, it doesn't support a ValueTuple since if I connect to the class itself then it connects. If this is the case, what is the workaround?
