Hi,
Thanks for your answer. Indeed I solved my issue just yesterday. While struggling now with code signing and building issues I planned to come here to give my solution and close this topic.
You’re right, the solution is to use netrc.
Finally, I have followed manual solution given by viktorbeney in this topic
Afterwards, in the workflow editor, I have replace SSH authentication step by the one with netrc. This is the crucial step and it works now like a charm.
I regret that netrc authentication is not proposed during “new app” workflow to manage my case. it would make things easier but everything works now. i can happily test and deploy my app
