🤔 Related to changesets/action#179 - I'm not certain what the right scopes are for updating version is at the moment...

[zimeg]

🗣️ No scopes need to be changed from the following!

node-slack-sdk/.github/workflows/release.yml

Lines 18 to 19 in 6cf7f13

The order of PRs beforehand caused this - a changesets PR didn't exist since our most recent release in 39949d1 and a @dependabot merge to workflows updated a workflow step version in 0de0777 after.

To fix this, I created the changeset branch from a local machine:

$ git checkout -b changeset-release/main
$ npm run changeset -- version
$ git add .changeset/ packages/
$ git commit -m "chore: release"
$ git push -u origin changeset-release/main

And a workflow reattempt worked - #2503! We we're hoping to bring the latest changes of main to this branch ourselves to avoid updating workflow permissions for now 🔏
