jx: bitbucket cloud cannot query pull request status

I tried doing promotion to a bitbucket cloud based environment and the PR is created fine but it then fails querying the PR status:

+ jx promote -b --all-auto --timeout 1h --version 0.0.2
Promoting app demo5 version 0.0.2 to namespace jx-staging-bb2
Using pipeline: jstrachan/demo5/master build: #2
Cloning into '/home/jenkins/.jx/environments/jstrachan/environment-jx-staging-bb2'...

Switched to branch 'promote-demo5-0.0.2'

I wonder if there’s a way to query the status for bitbucket? Maybe we have to use Jenkins itself to query the status if the bitbucket REST API doesn’t support it?
