shouldn't that be !"on-demand" to cover "provisioned-concurrency" as well?

Also, you can change s-c-function version from snapshot to 4.1.1 as we just had a release

See: https://docs.aws.amazon.com/lambda/latest/dg/configuration-envvars.html#configuration-envvars-runtime

AWS_LAMBDA_INITIALIZATION_TYPE – The initialization type of the function, which is on-demand, provisioned-concurrency, or snap-start.

For provisioned-concurrency it would also make sense to initialize the context earlier - therefore !("on-demand") would cover this as well.
