[BUG] traits are not working proper

[benkeil]

Describe the bug.

It's not possible to add message traits via references.

traits {
  trait {
    headersRef {
      ref("#/components/messageTraits/cloudEventHeaders")
    }
  }
}

produces

traits:
  - headers:
      $ref: "#/components/messageTraits/cloudEventHeaders"

but valid would be

traits:
  - $ref: "#/components/messageTraits/cloudEventHeaders"

The DSL does not allow to add refs.

Expected behavior

allow traits to be just references

Thank you for the report. I will work on a fix. The correct way to define a trait reference should be:

traits {
    reference {
        ref("#/components/messageTraits/cloudEventHeaders")
    }
}
