Error on updating a file

[ahmedk92]

I'm using this code to get the latest sha to update README.md:

const commit = await octokit.repos.getCommit({
                  owner: context.repo.owner,
                  repo: context.repo.repo,
                  ref: 'master'
               });
octokit.repos.createOrUpdateFileContents({
  sha: commit.data.sha,
  owner: context.repo.owner,
  repo: context.repo.repo,
  path: 'README.md',
  message: 'Update README',
  content: 'VGVzdCB0ZXN0',
  commiter: {
  name: 'update-readme-bot', 
  email: '[email protected]'
  },
  author: {
    name: 'update-readme-bot',
    email: '[email protected]' 
  }
});

But I keep getting this error:

Unhandled error: HttpError: README.md does not match <sha in commit.data.sha>

What sha should I get? and how to get it?

Thanks.

What you want is the file sha, not the commit sha. You can get the file sha using octokit.repos.getContents({owner, repo, path}). The response data includes sha, which is the sha you need to set when updating the file.

In the case of the repository's README, you can also use octokit.repos.getReadme({ owner, repo }). The response includes sha and also path which you can then use with octokit.repos.createOrUpdateFileContents, as different file names can be used for repository READMES, such as README, README.md or readme.md
