HI @RaymondGiorgi ,
Your notify commands do look straight forward. Are you using a legacy convenience image? If so, I’d recommend upgrading to a next-gen convenience image. You can read more about the deprecation of legacy convenience images here.
You can also try debugging with SSH or pinning the sha of the image used in a previously passing build.
Please feel free to share a build link or open a ticket and i’d be more than happy to have a closer look.
