"No script url provided” error in release mode

[Emilios1995]

Description

I created a new app with react-native init and tried to run it in release mode by changing the scheme.
The problem is that the app crashes immediately after opening it.
Xcode throws an error "No script URL provided"

I I've already checked the contents of the generated .app as described in this answer http://stackoverflow.com/a/41986215/1978520 and I found that the main.jsbundle file is not in there. I tried generating and adding it manually as described in this answer http://stackoverflow.com/a/41803596/1978520 but that didn't work

Reproduction Steps and Sample Code

Just making an empty project, but this only happens in my MacBook.

Additional Information

• React Native version: 0.42.3
• Platform: iOS
• Development Operating System: MacOS
• Xcode version: 8.2.1

Here is the full error displayed by Xcode:

Just notices this is because the packager is using the wrong version of node

@Emilios1995 : can you provide more info like which version of packager you were using and which was required ?
