I think the error code is related with the credentials and the proxies.
Did you set up the Proxy ?
When you click in the SQL server Agent platform you will see some displayed folders. One of those is Proxies--> SSIS Package Execution-->Right Button-->New Proxy.
There you have to set up a Proxy with the features and permissions to run the SSIS Projects with your credentials (First see if you have credentials assigned to your profile\domain).
Later you will have connect to the Integration Services and create a folder to host your package:
Click on Stored Package Folder-->MSDB->Right button-->New Folder.
And the last one is save your package in that folder using the package from the visaul studio clicking on File-->Save copy of package.dtsx as-->Package Location-->SSIS package storage and there you have to save it the server and the folder that you have created there.
Let me know if this works for you!
