[BUG] Parsing yields error due to correlation between a Channel and Operation

[g-radam]

Describe the bug.

The parser yields an error due to some correlation between a Channel address being null and its associated Operation not having traits: [] defined. Either changing the address to be not-null, OR, adding a traits: [] field to the operation will suppress the error.

Note that Operation Traits are NOT required by the spec, so being forced to add a traits: [] field to an operation due to a channel address being null is quite erroneous. I have zero insight into where such an issue could be stemming from.

Expected behavior

Traits can be omitted from operations without an error, regardless of if the associated channel has a null address.

How to Reproduce

Below is a minimal reproducible example:

asyncapi: 3.0.0
info:
  title: Acme Server API
  version: 1.0.0
channels:
  Exchange:
    address: nunotnullactually  <------------------- Make this null, and ensure there is NO `traits` on the operation, to cause the error
    messages:
      FooEvent:
        name: FooEvent
        title: Tenant Created
        contentType: application/json
        payload:
          type: string
operations:
  sendTenantCreated:
    title: Send tenant created event to client
    action: send
    #traits: []    <------------------------------------------ Adding this suppresses the error when address is null.
    channel:
      $ref: '#/channels/Exchange'
    messages:
      - $ref: '#/channels/Exchange/messages/FooEvent'
