Does this upcoming AWS change affect users of your CloudFormation templates? Probably we all received this email. Maybe you could explain, thanks.
Potential Action Required: Lambda Botocore Deprecation
We are contacting you regarding actions needed on your account(s) to prevent disruption to your CloudFormation stacks. Starting on April 01, 2021, AWS Lambda will no longer support the botocore.requests library in Python runtimes . If you are using the cfn-response module for a Lambda-backed custom resource, you must modify your Lambda function resource’s Code or Runtime property and update your stack(s) in order to get the latest version of the cfn-response module which removed its dependency on botocore.requests. If you do not update your Lambda function by April 01, 2021, you will no longer be able to create, update or delete your custom resource. If you are updating the Runtime property, please include the lambda:UpdateFunctionCode action in your IAM policy.
If you are hosting your Lambda function code from an S3 bucket, you can refer to the updated cfn-response module’s source code in our documentation . For more information on how to update lambda function can be found in knowledge center .
