I'm trying to run my pipeline, but getting error:

The 'default' section in your bitbucket-pipelines.yml file is missing a 'step'. Please add the missing 'step' to fix the error.

When I copy my bitbucket-pipelines.yml contents to https://bitbucket-pipelines.prod.public.atl-paas.net/validator - it's passing with VALID status.

The code also passes my pre-commit yamllint validation.

I've attached full pipeline file as an attachment.
