Unable to use backport

Nadie ha tomado este issue todavía.

I'm trying to backport https://github.com/mapbox/mapbox-gl-native/pull/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 #12128 release-chai`

Reproduce los tres comandos de backport indicados en el issue y, después, inspecciona el manejo de argumentos del comando y la ubicación referenciada de @octokit/rest validation.js en busca del error `number`. Se considera completado cuando el backport previsto del pull request 12128 a release-chai se ejecuta sin los errores indicados.
