Creating an app upload fails during validation

I realise this may not be an ionic related question but chances are that somebody here has experienced the same thing. I’m trying to release an update for an ionic app that’s in the app store. However, when I try to validate the app in xcode organiser, I get the following obscure error message.

Does anyone recognise this message or know what to do? Building the app in ionic has been a real pleasure so far, but getting the app in the appstore or get it updated in the store has been nothing but misery :smile:

Do you not get any more info of the error?
