We are currently getting a warning about digest updates, however when we look at the logs it is correctly resolving the digests. So i am not sure why we are seeing the error. This is occurring for custom manager which is updating a list of dependencies.

For reference my custom manager is:

{
      customType: "regex",
      description: "Update Cargo Dist Actions",
      managerFilePatterns: [
        "dist-workspace.toml",
      ],
      matchStrings: [
        "\"(?<packageName>.+\/?)\" = \"(?<currentDigest>[a-f0-9]{40})\" # v(?<depVersion>[0-9.]+)"
      ],
      datasourceTemplate: "github-tags",
      versioningTemplate: "semver",
      currentValueTemplate: "{{depVersion}}",
      extractVersionTemplate: "^v(?<version>.*)$",
      autoReplaceStringTemplate: "\"{{depName}}\" = \"{{newDigest}}\" # v{{newVersion}}",
      depTypeTemplate: "action",
    }

Hi there,
To the Discussion creator: please edit and improve the "Which version of Renovate are you using?" answer.
You've specified either latest or a major version number, but as Renovate ships many updates daily, the specific version of Renovate that runs changes.
You can find the specific Renovate version by checking the INFO: Repository started log line.
Thanks, the Renovate team
