Overview of the Issue

Doc says for mergeable https://www.runatlantis.io/docs/command-requirements.html#mergeable

we just check if there is a conflict that is preventing a merge

But atlantis plan fails for bitbucket.org (Cloud) when there is no conflict upon creating Pull Request

Above screen shot where there is no mentioning of conflict and its fully in-sync with main branch

Reproduction Steps

1. fork a new branch from up-to-date remote main branch
2. make changes on the forked branch
3. create a pull request to remote main branch
   Atlantis comments on PR saying Plan Error: Pull request is not mergeable

Environment details

• Atlantis version: atlantis:v0.23.5
• Deployment method: helm
• If not running the latest Atlantis version have you tried to reproduce this issue on the latest version:
• Atlantis flags: server

Atlantis server-side config file:

apiVersion: v1
data:
  repos.yaml: |
    repos:
    - id: bitbucket.org/XYZ/aws-infra-data
      plan_requirements: [mergeable]
      ...
      ...

But manually adding atlantis plan right after the error message, it proceeds to plan

[nitrocode]

Is this a recent bug? Have you tried an older version to see if this may be a regression?

[pavankumar-go]

this was my initial deployment, haven't tried any older version yet.

I faced the same issue with Bitbucket server. Temporarily disable plan requirement.

[velvetzhero]

Same issue here with 'github' and atlantis v0.26.0.

[brettpalmberg]

Good Evening. I just ran into the same issue with BitBucket Cloud using Atlantis v0.27.1.

On a New PR Created webhook (no merge conflicts in PR), Atlantis returns the following:

When I subsequently typed atlantis plan in a comment in the same PR, atlantis ran the plan successfully.

@brettpalmberg are you able to use apply_requirement: [mergeable] with bitbucket cloud? I've been struggling with this for some time and could not find any help either here or in the Atlantis community yet. For me it just ignores the mergeable state of the PR and run the apply even without any kind of approval. If you could maybe shed any light on this or share your config files, I would really appreciate it.

@oliver-vini - I had a similar experience, did not get this working. I removed the [mergable] requirement in the configuration file in the interim until the bug is resolved.
