I am trying to deploy my lambdas to AWS, but getting this error.

` An error occurred: AssignOrderLambdaFunction - Unable to retrieve TopicName attribute for AWS::SNS::Topic, with error message Rate exceeded (Service: Sns, Status Code: 400, Request ID: 79f1648a-90e0-5ebf-bb34-3f0993f6ca08).`

I did not change anything in the serverless.yml. I have used this serverless.yml for over two years and have had no issues. Please help if you have any info about this error.  
BTW I am not an AWS expert, just using it 🙂

Here are some details:

- I am using Lambda with NodeJs (Typescript)
- Using SNS and SQS to pass events across my services.

My serverless.yml structure:
