Action on self-hosted MacOS runner fails with GITHUB_OUTPUT: unbound variable but release is created

[avsaase]

I'm running this action on a self-hosted MacOS runner and I'm getting this error when I try to make a release.

/Users/alexander.vansaase/dev/actions-runner/_work/_actions/taiki-e/create-gh-release-action/v1/main.sh: line 118: GITHUB_OUTPUT: unbound variable
Error: Command failed: bash --noprofile --norc /Users/alexander.vansaase/dev/actions-runner/_work/_actions/taiki-e/create-gh-release-action/v1/main.sh

Even though the action fails, the release is created.

Here's my release.yaml:

name: Release

      - v[0-9]+.*

Fixed in 1.6.2. Thanks for the report!
