When I edit my .xml file to include the requisite settings to deploy my app engine app as a managed vm, I get this error:
App Engine service account has insufficient permissions for project. Developer or owner required. Version: 30.388785162679429162
Rolling back the update.
Project is parasql-app if that helps you.
Note I am deploying as the owner of the project via Eclipise 1.9.28 sdk. Deoplying as regular app engine (non-managed VM) works fine.
