How to fix a JavaScript runtime error: Unknown runtime error in UWP application?

I am using Windows Runtime Component to fetch data from SQL server. After adding the reference to component I am trying to assign the value (that i am getting from method in Windows Runtime component (C# code)) to javascript variable but it is throwing error.

0x80131040 - JavaScript runtime error: Unknown runtime error.

This error occurs when I set the minimum version to Fall Creator's Update (build 16299).

If I run this code by setting min version to 10240, then i am getting error:

Could not load file or assembly 'System.Data.SqlClient'.

After searching on google I found System.Data.Sqlclient is not supported in earlier version. URL suggested to set min version to 16299 is https://docs.microsoft.com/en-us/windows/uwp/data-access/sql-server-databases

How can I fix this?
