@charlie-haley Can you share a sample of deployment.template.json and folder structure for your project? Something in your deployment.template.json should be inconsistent with your folder structure, so the task failed to figure out images need to be pushed (just imagine there’s a dummy module in your project, which won’t be built in your pipeline). I can share how to adjust the deployment.template.json or your folder structure.

I got the same problem. @prativen @blackchoey any progress on this issue so far?
