  <p>I tried opening the application in both Visual studio 2017 and 2019 and I getting the same error in both versions of Visual studio. I also tried to change the typescript version in Visual studio itself, but that didnt work either. Below is the screen shot from Visual studio Typescript version:</p>

  <p>any help in resolving this error will be greatly appreciated.</p>
