Container image verification failed

[JanetZhouJ]

What is not working as expected?

When verifying the signed container image with notation I am getting the error

What did you expect to happen?

I just test notation for a new build image and it work error and the reason describe is mismatch Content-Length, but I check nginx for harbor, it has not error and the request code is 200, so what means about mismatch Content-Length

How can we reproduce it?

First notation cert generate-test --default "registry-ops.cokutau.com"
notation sign --signature-format cose registry-ops.cokutau.com/dev-pjcxa/botstudio:20240906_152011 --- it works goods

notation ls registry-ops.cokutau.com/dev-pjcxa/botstudio:20240906_152011

Hi @JanetZhouJ ,

To troubleshoot the verification issue, can you please share the manifest metadata of your signed image? Maybe you can use ORAS tool to get the manifest metadata:

oras manifest fetch registry-ops.cokutau.com/dev-pjcxa/botstudio:20240906_152011
