[Maradani Revat1]

Hi,

I had a requirement to add a throw if the app name is null and in throw i need to display catch message. can anyone pls help me how to write the throw block and display the error message from catch block. Below is the script.

try {
    var recentAppJson = {};
    var appName = '';
    
   recentAppJson.success = true;
} catch (ex) {
    recentAppJson.error = ex.stack;
    recentAppJson.success = false;
}

Hi

It seems you are not familiar with the concept of exception handling. When someone ask you to throw an exception then you should implement something like this:

function foo(strAppName) {
    if (typeof strAppName != "string" || strAppName.length == 0) {
        throw new IllegalArgumentException(
            "Expected a non-empty 'string' argument."
        );
    }
}

So the caller of the function foo() is responsible to catch the exception:

try {
  foo();
}
catch (e) {
  gs.info(e.toString);
}

Hi

basically not, but it is always the best approach to encapsulate business logic in functions (located in Script Includes).
