This is exactly what the problem was.

I’m having a similar issue, but I’m pretty sure mine is not being caused by team permissions. Here’s my CODEOWNERS file (with org and team name anonymized):

# This file is used to automatically request reviews on PRs.
These owners will be the default owners for everything in
the repo, unless a match on a later line takes precedence.
"@MyOrganization/MyTeam" below requests review from all members of MyTeam.

@MyOrganization/MyTeam

It's also possible to add notifications based on language
or location in repo, etc.
More info at docs: https://help.github.com/articles/about-codeowners/

However, when I make a PR in a repo with that CODEOWNERS file, no members of the team are notified for review. After seeing @notmessenger’s message from GitHub Support saying that the team needs write permissions for the repo, I verified the team had write permission for the repo, but subsequent PRs still do not kick off a review request by team members.

Am I missing something else? I can replace the “@myorganization/MyTeam” part with a list of all the team users and reviews are automatically requested, but I want to be able to do this on a team basis, not on a user-by-user basis.

The only other two confounding factors I can think of are these:

1. The team name’s capitalization is kinda funky. Clicking through the org’s team list, I can see the team capitalized in some places (MYTEAM), lowercaps in others (myteam). Asking our admin to hit the GitHub API, I found that the team’s “name” field is MYTEAM, whereas its “slug” field is myteam. But at this point I’ve tried using both capitalization styles in my CODEOWNERS file and neither has worked, so that shouldn’t be it.
2. In the org, the team is marked as a “Secret” team. (Mousing over the “Secret” box, a tooltip appears and says “Only visible to its members.”) If it’s necessary, I can talk to admin and see if we can remove the team’s “Secret” designation, but I’d rather avoid that.

I’m having this problem also.

• My team is “visible”.
• My team has “Write” access to the repository.

I’m not sure what else to try.

• My organization is private. Could that be a problem?
• My organization name is not all lowercase. Could case sensitivity be a problem?
  • A note here, I’ve tried both “AdCellerant” and “adcellerant” variants with no luck. If this is the problem, it likely resides within github.com.

I have this issue both in my CODEOWNERS file and when trying to use hub.

BTW, the team I’m trying to hook up is @AdCellerant/app.

CODEOWNERS

I know this worked in the past. It stopped working the day I added app/renovate-approve. Since then, it doesn’t, even when I remove app/renovate-approve. I’m stumped.

Hub

I know this part is unrelated but I’m hoping it’s helpful…

I’m trying to assign team reviewers via repo-sync/pull-request@v2 which uses hub under the hood.

This is the API call that fails. (Hub executes the POST.)

Ours just started having this issue as well. We switched from having a lot of members to having teams with members (at at least the top level team i’m on is definitely visible), and now our PRs don’t have CODEOWNERS properly assigned either.

Was there ever a fix to this? Seems that granting the team write access wasn't enough for some to fix this behavior.

Having same problem. Team has write access, is also visible not secret, but still no one is assigned from a team.
