The App cannot be installed because its integrity could not be verified (Apple Configurator)

So for testing purposes I am attempting to install my own app via Apple Configurator. its a very large App, but that should not be a problem. However, it gets stuck approx 3 quarters of the way and then goes "blank" and claims that its integrity could not be verified. is this an error with Apple Configurator or do i need to do something to fix this?

Does it install via Xcode on the same device?

Maybe you need to go to your device's Settings > General > VPN & Device Management to 'trust' the profile?
