Gitlab-CI rules syntax with regex and project name

I am attempting to upgrade our except/only syntax to use rules instead in preparation for the upcoming upgrade.

Here is the original syntax. Notice the @ and then the repo/project are specified. This allows me to ignore branches created on forks of the repository.

    - /^release\/v\d+.\d+.\d+$/@myCompany/myProject

When migrating that to use the new rules syntax I am attempting the exact same thing but it fails with an error seen below:

    - if: $CI_COMMIT_BRANCH =~ /^release\/v\d+.\d+.\d+$/@myCompany/myProject
      when: always

jobs:build_feature:rules:rule if invalid expression syntax

For some reason the new rules syntax doesn’t like this regex and I’m not sure how to achieve the same thing using rules.

I’m a doofus. Here is how I was able to do it (it passes validation but haven’t actually tested the full thing yet)

    - if: $CI_COMMIT_BRANCH =~ /^release\/v\d+.\d+.\d+$/ && $CI_PROJECT_PATH == "myCompany/myProject"
      when: always
