@dpwdec The JSON Schema document sets the queue property as required. See https://github.com/asyncapi/spec-json-schemas/blob/master/bindings/sqs/0.2.0/channel.json#L33

So perhaps it is a matter of fixing the examples instead? Please @iancooper could you help figuring out if we should keep queue field as required or not? 🙏

@smoya Sorry for my slow reply. I think the examples are correct and there should be an option for users to configure sqs: {} to indicate the protocol for documentation purposes without being forced to provide specific infrastructure configuration.

@iancooper I think the primary example that's currently committed covers this. The need arises if you are using point to point SQS. When using a p2p queue you configure information about that queue at the channel level (as opposed to the operation level) but then you will still want to include an operation (publish / subscribe) to indicate the protocol for the message and $ref to a message and schema (which only lives under the operation).

Below I've reproduced the example as it is in the current specs but added the message $ref to illustrate the need.

user-signedup:
    bindings:
      sqs:
        queue:
          name: user-signedup-queue
          fifoQueue: false
          receiveMessageWaitTime: 4
          redrivePolicy:
            deadLetterQueue:
              name: user-signedup-dlq
          policy:
            statements: 
            - effect : Allow
              principal: *
              action: Sqs:SendMessage
            - effect : Allow
              principal: *
              action: Sqs:ReceiveMessage
        deadLetterQueue: 
          name: user-signedup-dlq 
          messageRetentionPeriod: 1209600
          fifoQueue: false
      subscribe:
        operationId: sendMessage
        description: sends messages when a user has signed up
        bindings:
          sqs: {}
        message:
          $ref: #/some/message/path

Below is how the JSON schema currently requires the operation to be configured, with the empty queues: [] property:

user-signedup:
    bindings:
      sqs:
        queue:
          name: user-signedup-queue
          fifoQueue: false
          receiveMessageWaitTime: 4
          redrivePolicy:
            deadLetterQueue:
              name: user-signedup-dlq
          policy:
            statements: 
            - effect : Allow
              principal: *
              action: Sqs:SendMessage
            - effect : Allow
              principal: *
              action: Sqs:ReceiveMessage
        deadLetterQueue: 
          name: user-signedup-dlq 
          messageRetentionPeriod: 1209600
          fifoQueue: false
      subscribe:
        operationId: sendMessage
        description: sends messages when a user has signed up
        bindings:
          sqs:
            queues: []
        message:
          $ref: #/some/message/path

To my eyes this looks more strange and confusing. You don't really want to indicate an empty list of queues (confusing) or information about the queue which is already on the channel (duplication). I suppose it could be omitted entirely but that presents a different set issues in terms of clarity of the protocol you are using with the message.

Hope this makes sense.
