Trivy Scan Always fails : failed to download vulnerability DB

Question

I am trying to run a Trivy Scan from within CircleCI and always get the same problem. I keep disabling this, but clearly scanning the containers is useful.

Suggestions on 'google' say that you need to use a GITHUB_TOKEN to stop rate limiting, but, I am using a GITHUB_TOKEN, as you can see in the debug - maybe it is the wrong one, as it is my TOKEN for my (Private GitHub) project. How do you get around this issue? Can I download and install the DB with a curl or similar first?

Version:

aquasecurity/trivy info found version: 0.16.0 for v0.16.0/Linux/64bit

Command:

trivy --light --token dummy -d -s "UNKNOWN,MEDIUM,HIGH,CRITICAL" --exit-code 1 ${IMAGE}

Error:
