The resources and data sources in this provider are generated from the CloudFormation schema, so they can only support the actions that the underlying schema supports. For this reason submitted bugs should be limited to defects in the generation and runtime code of the provider. Customizing behavior of the resource, or noting a gap in behavior are not valid bugs and should be submitted as enhancements to AWS via the CloudFormation Open Coverage Roadmap.

Expected Behavior

SQS Inline policy is created and attached to sqs queue.

Actual Behavior

AWSCC provider failed to create the policy resource with following error:

awscc_sqs_queue_inline_policy.test: Creating...
╷
│ Error: AWS SDK Go Service Operation Incomplete
│ 
│   with awscc_sqs_queue_inline_policy.test,
│   on main.tf line 18, in resource "awscc_sqs_queue_inline_policy" "test":

Possible Cause

Looking at the CloudTrail events


    "eventTime": "2023-08-28T17:56:59Z",
    "eventSource": "sqs.amazonaws.com",
    "eventName": "SetQueueAttributes",
    "awsRegion": "us-west-2",
    "sourceIPAddress": "cloudformation.amazonaws.com",
    "userAgent": "cloudformation.amazonaws.com",
    "errorCode": "InvalidAttributeValue",
    "errorMessage": "Invalid value for the parameter Policy.",
    "requestParameters": {
            "attributes": {
                    "Policy": "{\"Version\":\"2012-10-17\",\"Statement\":\"[{\\\"Action\\\":\\\"sqs:*\\\",\\\"Effect\\\":\\\"Allow\\\",\\\"Principal\\\":\\\"*\\\",\\\"Resource\\\":\\\"*\\\",\\\"Sid\\\":\\\"Stmt1693245053186\\\"}]\"}"
            },
            "queueUrl": "https://sqs.us-west-2.amazonaws.com/xxxxx/terraform-awscc-queue-example"
    },

for the above Action from CloudControl API in the backed it is making a SetQueueAttributes API call which supports Policy as the acceptable request parameters but awcc provider is sending policy_document as the request parameter and henceforth resulting in invalid request.
