Help deploying my first app in Shiny for Python

I am trying to deploy a very simple shiny app using python. I previously got it working but now I keep getting an error "[ERROR]: Application deployment failed with error: Unhandled Exception: Child Task 1345041128 failed: Error building image: Build exited with non-zero status: 1".

Can anyone please help me with this? It is so simple and I just want to get one small app up and running but I've been stuck for the past 3 weeks

Well, this error can be caused by network and firewall issues, which means you must ensure about it. You can also check other things like checking your docker file, checking missing files and if still it doesn't work then go for contact support.
