Pipeline Definition not discovered

Hi,

I was trying to use Pipelines, I followed the documentation however my created pipeline definition doesn't seem to be picked up. I've tried many variations from my desired Docker image to the current "Hello World" pipeline. The bitbucket-pipelines.yml is picked up in the Settings ("View bitbucket-pipelines.yml" is clickable and directs me to the correct file), however the Pipelines page remains blank.

I checked existing issues with the "Pipelines" component, however I couldn't find anything similar hence I'm raising this issue.

Repo: https://bitbucket.org/winnovations/jakworkspace\\
Pipeline: https://bitbucket.org/winnovations/jakworkspace/addon/pipelines/home#!/

Thanks,
Adam
