Motivation

Follow up from #12297, we did not pass the QueueUrl to GetQueueAttributes but rather the QueueArn. This actually still worked somehow because SQS took it as the QueueName and was able to resolve it.
However, when working with cross-account, this did not work because we were not able to resolve to the right account id.

I thought of doing an internal connect_to().sqs.get_queue_url(QueueName=name, QueueOwnerAwsAccountId=queue_account), to get the proper QueueUrl, but if the queue did not exist, it would have raised without triggering an IAM check for GetQueueAttributes, so the IAM parity would not be there... so I resolved to build a dummy value instead, as it is not very important and we only need SQS to be able to parse it.

Upstream run: ✅ 13658265278

Changes

  • build a dummy queue url from the queue ARN to pass to GetQueueAttributes.

Thank you for coming up with this innovative workaround @bentsku 🧠

what a coincidenc that it worked in the first place 😅

localstack-core/localstack/services/lambda_/provider.py
# which is not given directly. We build out a dummy `QueueUrl` which can be parsed by SQS to return
# the right value
queue_name = arn["resource"].split("/")[-1]
queue_url = f"http://sqs.{arn['region']}.domain/{arn['account']}/{queue_name}"

Interesting hack. I wonder how AWS does it internally because GetQueueUrl is not a required IAM permission: https://repost.aws/knowledge-center/lambda-sqs-event-source

Yes, I really wonder too.. maybe just rebuilding the queue manually like us, but it seems… weird 😅 I don’t know if there would be any other operation that sqs:getQueueAttributes permission would give access to. Thanks for the review!
