how to handle error occurred when getFolderAsync?

Question

Hello,

I'm using storage.getFolderAsync method to find a folder like below

try{
                storage.getFolderAsync('CERT').then( function (folder) {
                    var x=1;
                }, function (e) {
                    var z = 1;
                }, function (f) {
                    var k = 1;
                });
            } catch (e) {
                Debugger.displayDebugMessage(e);
            }
            finally { }

It works when there is a 'CERT' folder but it throws a runtime-exception when the folder does not exist. 

The message is: "JavaScript runtime error: The system cannot find the file specified."

 

How could I run the application through the error?

 

Thanks,

Hi Sungsoo,

This is the correct code.  The try catch block will allow your application to continue to execute.  Try running your application, but not with the debugger and see what happens.
