S3 access denied problem in pipeline step of pipeline deployment



I'm seeing an error when my pipeline is trying to upload my package to S3 bucket. I get this error reason, Deployment <an id> failed because Couldn't call cloudformation for target <target name> because of a validation error. The error was S3 error: Access Denied For more information check http://docs.aws.amazon.com/AmazonS3/latest/API/ErrorResponses.html (Service: AmazonCloudFormation; Status Code: 400; Error Code: ValidationError; Request ID: <request id>; Proxy: null)

Is there a way for me to resolve this? Thanks

Are you using IAM permissions to access the S3 that you are referencing in CloudFormation?
Also, is access denied due to S3 bucket policy?
Another possibility is to check whether the S3 URL specified in CloudFromation is correct.
