Ionic Appflow build fails with "Permission denied"

Question

I am trying to build my project on Ionic Appflow, but it keeps failing with the following. I do not understand what could be wrong as I can locally generate and build locally.

Has anybody else experienced such issues?

sh: 1: ng: Permission denied
npm ERR! code ELIFECYCLE

If you did the project in Windows, it is possible that it is a permission error on the generated files. Why AppFlow uses a Unix OS for Android.

You have to give it permissions through GIT:
