AWS ECR manifest not found on inspection #30
Description
When using imagetools inspect right after the image has been built, sometimes the manifest cannot be found: https://github.com/docker/github-builder-experimental/actions/runs/19393242225/job/55489688577#step:12:70
Upload to transparency log: enabled
Using Sigstore signing endpoint: https://fulcio.sigstore.dev/
Error: Signing BuildKit attestation manifests failed: ERROR: httpReadSeeker: failed open: content at https://public.ecr.aws/v2/q3b5f1u4/test-docker-action/manifests/sha256:76bc7984bdcf00ef5af953b7cb3de57ef39101cc091f4913c738b16cfbd26e53 not found: not found
It seems to happen only with AWS ECR so maybe something racy on their registry.
I will add more debug in our actions-toolkit: https://github.com/docker/actions-toolkit/blob/bb9028cd44bba32a70273d625d310a8deaa37072/src/buildx/imagetools.ts#L65
