[bug] GraphQL repositoriesContributedTo doesn't count repos where I'm author (and not commiter)

Hello,

When I run the following GraphQL query to the Github API:

{
  user(login: "bokub") {
    repositoriesContributedTo(first: 100, contributionTypes: [COMMIT]) {
      nodes {
        nameWithOwner
      }
    }
  }
}

I see all the public repositories I’ve contributed to, except a few that are missing.

After a short investigation, I’ve realized that I don’t see repositories where I’m author but not commiter

For example: (open the links to see the commits)


Can you confirm that it’s a bug? Or is it expected?

Thanks
