Latest Version

I could reproduce the problem in the latest build

What happened?

We fail to parse manifest information from the dockerhub registry as returned API response is in a different schema, we are currently expect Image Manifest V 2, Schema 1 but the API returns Image Manifest V 2, Schema 2

Reproduction

Ensure verbose logging is enabled

1. Create a docker hub feed
2. Create a deployment process that references a official docker image e.g. nginx
3. Deploy

Error and Stacktrace
