unable to access sqs queue from ecs task

I'm trying to understand how this worked. When I run it i'm able to create the SQS task and launch the task but when the ECS task tries to read from the queue it gets the following error, which I have reproduced by logging into the shell script container (after preventing it from exiting):

root@f9910bdcd9d6:/# aws sqs receive-message --queue-url=https://queue.amazonaws.com/831754492748/ecs-test-plepeskaQueue --region=us-east-1

An error occurred (AccessDenied) when calling the ReceiveMessage operation: Access to the resource https://queue.amazonaws.com/ is denied.

And this makes sense b/c although I can see that the ecsInstanceRole has a policy that gives it access to the S3 bucket I can't see where it is given access to the SQS queue.

Has something changed since this worked? Or, is there another reason why access to the queue is denied?
