Lambda function must not use a deprecated runtime

High AWS General aws-lambda-function-lambda-function-deprecated-run

Applies to

AWS::Lambda::Function

What CGPulse checks

A resource passes this rule when runtime must not be one of ["python2.7","python3.6","python3.7","nodejs10.x","nodejs12.x","nodejs14.x","dotnetcore2.1","dotnetcore3.1","ruby2.5","ruby2.7","java8"]. Anything else is reported as a finding with the evaluated property value attached as evidence.

How to fix it

Upgrade Lambda function to a supported runtime to receive security patches. In AWS Console: Lambda > Functions > Configuration > Runtime settings > Edit. See: https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html

Terraform

resource "aws_lambda_function" "{name}" {
  runtime = "python3.12"  # Use a supported runtime
}
