Describe the bug.

I'm getting error like this:

after using .validate() method on AsyncAPI document that contains operations with channel and messages components specified like the one below(without using $ref)

sendBranchCreatedToAnalyticsExchange:
    action: send
    channel:
      address: analytics
      messages:
        branchCreatedMessage:
          title: Branch created message
          summary: Event fired after a branch is created.
          payload:

              - type: object
                properties:
                  type:
                    type: string
                    const: something.branch.created
                    example: something.branch.created
                required:

      bindings:

              properties:
                id:
                  type: string
                  description: Event ID.
                  pattern: '^evt_[0-9abcdefghjkmnpqrstvwxyz]{26}$'
                  example: evt_01h1s5z6vf2mm1mz3hevnn9va7
              required:
                - id

        cc:
          - branch.created
        ack: false
