Unable to deploy to Container Apps

I am trying to deploy an image from DockerHub. Is this supported? I am getting the same error that others are having. I created a service connection to it and can push an image, but I run into problems when I try to deploy a new container version. I have connections to ARM and Dockerhub set up and verified.

```
