Example of setting up AWS lambda function with VPC and NAT

Add Warning: NAT Gateway not covered by Free Tier

So I used this example without knowing that NAT Gateways are not covered under AWS's free tier, which in about two weeks racked up $30 in charges.

Please add a note to the README for this project warning developers that they can be charged a significant amount of money by deploying this code. I can only imagine what would have happened if I had deployed this and left it up all month.

AllocationId: Fn::GetAtt: ... doesn't seem to be working for me

I know this is a really old serverless configuration, but any help would be appreciated, if you even still deal with this domain of problems.

Fn::GetAtt:

This is the error I'm getting on my end, using the configurations suggested in this example service:

✖ Stack address-validation-prod failed to deploy (103s)
Environment: darwin, node 16.13.2, framework 3.0.0 (local) 3.2.1v (global), plugin 6.0.0, SDK 4.3.0

Error:
CREATE_FAILED: NatGatewayLambda (AWS::EC2::NatGateway)
Value of property AllocationId must be of type String

Requires two non-empty parameters

I got the following when I tried with serverless framework

The CloudFormation template is invalid: Template error: every Fn::GetAtt object requires two non-empty parameters, the resource name and the resource attribute

Please let me know solution to fix this issue.

NAT Instance instead of NAT-Gateway

The current examples uses a NAT-Gateway. Is it possible to replace it with a NAT-Instance?
With the usage of a NAT-Instance the monthly costs can be reduced compared to the NAT-Gateway.
