Access denied to SQS via AWS SDK
Make sure that both the following policies allow access to the SQS queue
- Resource (SQS) based policy: The SQS queue should allow your identity to use the queue. You define this using the queue policy (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/quickref-iam.html#scenario-sqs-policy). The default queue policy will allow access only to the owner of the queue (owner of the queue is the identity that created the queue).
- Identity based policies: The policy for the identity that is accessing the queue should have permission to invoke operations on the queue.
Make sure that the access is not restricted by either one of them.

After digging I discovered that the account I was using wasn't granted the access to SQS service.
To give a SQS access to an account you have to go to the amazon management console. Then click on IAM. Under this section click on Users and then you can manage permission for each account you created.
I had the same strange issue, I had everything set up including policies and permission, after a couple of hrs I found out I was getting 403 error because of wrong aws region was configured in my application it was supposed to be ap-south-1 by default it was us-east-1
