Update Deprecated Lambda Runtimes nodejs 12.x

[constseche]

The following stacks:

1. env-aws-sso-extensions-for-enterprise-preSolutionArtefactsStack
2. env-aws-sso-extensions-for-enterprise-solutionartefactsStack

create lambda functions (names are env-aws-sso-extensions-fo*) with deprecated runtimes nodejs12.x

we need to update them nodejs16.x

Hi @constseche , we had already updated Lambda runtimes for all lambda functions that are created specifically for the solution. The lambda functions that you see in those 2 stacks using nodejs 12.x are provider functions that CDK deploys by default in an AwsCustomResource construct. We use this for cross-account and region SSM parameter reading

There's already an issue being tracked in aws/aws-cdk#19117 , and as and when the CDK provider is update to a newer runtime, we will upgrade our solution to use that CDK version.

Hope this helps. Please let us know if you need any other data
