Hi,

typescript also has the try & catch properties.
let result;

catch(e){
    result = (e as Exception).Message;
}

Use a generic response class to simplify the communication model.
Try to return the response from your C# method with a proper status and message format,
so that you can check the status = sussess or error and you can receive a success and error message also.

{
status:"error"
message: "invalid exception."
}

Now, call the C# endpoint from typescript and you will receive the same message here.

You can also user strongly type try/catch blocks in TypeScript. For more information check code examples:
