Exported OSX app for testing triggers App Store login and fails to launch

Hi,


I'm following these steps to create an app for testing purposes, by exporting a Development-Signed application: https://developer.apple.com/library/content/documentation/IDEs/Conceptual/AppDistributionGuide/BetaTestingYourMacApp/BetaTestingYourMacApp.html


But executing the generated app on a development device (running 10.12.3) triggers a sign-in dialog in the App Store app (The device was properly added to the portal):



Then, If I login with my apple ID, the app fails to load with the error : "is damaged and cannot be opened"



Notes:


Running codesign --verbose=4 --deep --strict ./MyApp.app/ succeeds

Running spctl --assess --verbose ./MyApp.app/ fails with

./MyApp.app/: rejected


This is what I tried to do to work around the problem:


1) Cleared and re-downloaded the profiles

2) Made sure all test devices were propertly added

3) I'm using the default, automatic 'Mac Team Provisionning Profile'. Tried with a manual profile to no avail.

Any ideas?
