How are you running Renovate?

A Mend.io-hosted app

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

I am using Renovate GitHub Action on GitHub Enterprise Server and I recently updated my docker build for my images in a private artifactory repository to support multi-arch.

Since then, renovate is failing to update image with the below error:

 "err": {
         "message": "Schema error",
         "issues": {
           "manifests": {
             "0": {
               "mediaType": "Invalid literal value, expected \"application/vnd.docker.distribution.manifest.v2+json\""
             },
             "1": {
               "mediaType": "Invalid literal value, expected \"application/vnd.docker.distribution.manifest.v2+json\""
             }
           }
         }
       }

I did a skopeo inspect on my image and here'e the output:

{
  "schemaVersion": 2,
  "mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",
  "manifests": [
    {
      "mediaType": "application/vnd.oci.image.manifest.v1+json",
      "size": 1807,
      "digest": "sha256:xxxxxxxxxxxxxx",
      "platform": {
        "architecture": "arm64",
        "os": "linux",
        "variant": "v8"
      }
    },
    {
      "mediaType": "application/vnd.oci.image.manifest.v1+json",
      "size": 1809,
      "digest": "sha256:xxxxxxxxxxxxxx",
      "platform": {
        "architecture": "amd64",
        "os": "linux"
      }
    }
  ]
}

I was going through the renovate code and the issue is with these lines of codes:
Link

export const DistributionListManifest = ManifestObject.extend({
  mediaType: z.literal(
    'application/vnd.docker.distribution.manifest.list.v2+json',
  ),
  manifests: z.array(
    Descriptor.extend({
      mediaType: z.literal(
        'application/vnd.docker.distribution.manifest.v2+json',
      ),
      platform: OciPlatform,
    }),
  ),
});

manifests.mediaType should be an ENUM with application/vnd.docker.distribution.manifest.v2+json & application/vnd.oci.image.manifest.v1+json instead of just a literal of former.

Are the manifests otherwise compatible?

it seems your builder is creating a wrong manifest list. you should update the tool to create a conform oci manifest list. the docker types are deprecated in favor of the oci media types.
