Run it in zp and check the log, got this "Run HTTP actionaction group id: c08a504f-ea49-45d4-b44b-69204c0de76b Timeout period has expired ResourceDownloader.GetResult."
When I use Run program action to run a hello.mp3 file, the mp3 music is playing normally. But the template stops and I get this error "Object reference not set to an instance of an object."
