Unhandled exception. System.InvalidOperationException: Each parameter in the deserialization constructor on type 'BL.Core.Command' must bind to an object property or field on deserialization. Each parameter name must match with a property or field on the object. Fields are only considered when 'JsonSerializerOptions.IncludeFields' is enabled. The match can be case-insensitive.
