You can see this PR working [here](https://github.com/getsentry/action-release/actions/runs/4833388053/jobs/8613330988?pr=155). If the action executes and there's never been a release before, it will fail. Adding `ignore_missing` fixes it: ``` When the flag is set and the previous release commit was not found in the repository, will create a release with the default commits count instead of failing the command. ```
