https://github.com/maheshvarak89/aws-cfn-templates/blob/master/s3_event_sqs

I am facing following error:

The ARN is not well formed (Service: Amazon S3; Status Code: 400; Error Code: InvalidArgument; Request ID: XXX03XXXXBC36E49; S3 Extended Request ID: bYBRrz0ybftGFwHxFCBXWBI5nRF15COGCL6Q8tm3bNs/e+aWafy+pAIIeUNy82DmOKJcVq1MthE=

Answer 1

An ARN for SQS is in the form

arn:aws:sqs:${Region}:${Account}:${QueueName}

You current ARN is of the form

arn:aws:sqs:::${QueueName}

Answer 2

Instead of building the ARN, you can simply reference it using GetAtt:

Queue: !GetAtt MyQueue.Arn
