The runtime parameter of nodejs12.x is no longer supported for creating or updating AWS Lambda functions while using AwsCustomResource.

[yaseen104]

In our project we are using AwsCustomResource .

const awsSdkCall: cr.AwsSdkCall = {
     service: 'KMS',
     action: 'replicateKey',
     physicalResourceId: cr.PhysicalResourceId.of('CustomResource::KeyReplicaCreation'),
     parameters: {
       KeyId: keyId,
       ReplicaRegion: replicaRegion
     }
   };

new cr.AwsCustomResource(this, `${replicaRegion}-custom-resource`, {
  onCreate: awsSdkCall,
  onUpdate: awsSdkCall,
  policy: cr.AwsCustomResourcePolicy.fromStatements([
    new iam.PolicyStatement({
      effect: iam.Effect.ALLOW,
      actions: ['kms:*'],
      resources: ['*']
    })
  ])
});

`
Now we know that nodejs12.x is not supported, but where can we provide the lambda runtime value?
We have checked the props and there is no way to provide it?

If you update to latest version, it shouldn't be using node 12 anymore.

For a list of supported runtimes, see https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html

Node 12.x was officially "phase 2" deprecated on May 30th, 2023 such that no lambda functions may be created or updated using that runtime.
