"Changes to a deployment package [for an AWS Lambda function] in Amazon S3 or a container image in ECR are not detected automatically during stack updates. To update the function code, change the object key or version in the template." https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-lambda-function-code.html

Change the S3 object key or the S3 version in the CloudFormation template before updating the CloudFormation stack. C. Upload the zipped source code to another $3 bucket before updating the CloudFormation stack. By changing the S3 object key or the S3 version in the CloudFormation template, CloudFormation will detect the changes and update the Lambda function accordingly. Additionally, uploading the zipped source code to another S3 bucket before updating the CloudFormation stack will also result in the Lambda function being updated.
