Commit message trigger firing on commit_messages

Question & Answer Builds

I have just had a build triggered that I don’t think should have run when a commit was pushed to a GitHub PR.

I’ve checked that there are no triggers for the specific workflow in Bitrise. There is a project-based legacy push trigger with a commit message regex, but the regex that doesn’t match the commit message.

I took a look at the build parameters and saw this:

{

    "commit_hash": "b3b3c09673a36e114bc597134ba7b8d898401614",
    "commit_message": "Address PR comments. Refactoring.",
    "commit_messages": [
        "feat(profile): user ID display, restore purchases, progress code entry (#22)\n\nCo-authored-by: Olivier Castille <96414603+ocastille@users.noreply.github.com>",
        "build: update version to 1.4.9(3)",
        "feat(lesson): add new word lesson overlay support (#24)",
        "build: update version to 1.4.9(4)",
        "Merge branch 'develop' into new_reward",
        "Address PR comments. Refactoring."
    ],

The regex matches a commit message that starts “build: update version…”. Has the trigger looked all the way through commit_messages to do the match? I’d only expect it to look in commit_message.

If the trigger is looking in commit_messages as well as commit_message, is there a way to make the trigger only look at commit_message? Otherwise I’ll need to make the build trigger from tags.
