Unable to use backport

[tobrun]

I'm trying to backport mapbox/mapbox-gl-native#12128 to release-chai, but not able to get it working. Probably doing something very trivial wrong here. These are the commands I tried:

backport ddc4b03c3416f1442a1e177ff5f7de7bf2a8e707 release-chai

{ Error: 'number' cannot be null

backport https://github.com/mapbox/mapbox-gl-native/pull/12128 release-chai

{ Error: no reference found for shorthand 'release-chai' errno: -3, errorFunction: 'Reference.dwim' }

backport #12128 release-chai

Not enough non-option arguments: got 0, need at least 2

I think the error may be that you have ever checked out release-chai locally, so there's no local branch checkout; only a remote.

Backport should use the remote branch as base over the local branch.

I made it a bit further, but backport still failed before submitting a PR with:

@mourner Does your GITHUB_TOKEN have permissions to create a pull request?

[mourner]

@jfirebaugh there's nothing mentioning PRs or seeming relevant in the permissions list: nevermind, looks like I haven't checked "repo - public_repo". It would be nice to mention it in the readme.
