I update NX and related versions. so now using node 14.15.0 instead of node 12.20.2

node version updated. so I update the aws-cdk packages. but now the following command is not working anymore. the issue is the optional chaining operator in aws-ec2.

npx env-cmd -f pipeline.json npx ts-node --project ./scripts/tsconfig.json ./apps/cloud-infrastructure/src/bin/pre-build.ts

I get the following error when I fire the above command.

node version 14.15.0. (tried in another version as well)

What's your TS version?
4.2.4 @Richard Dunn
What have you set as the target in ../tsconfig.base.json?
As I mentioned, that tsconfig isn't being used when compiling that JS. Also, that version of node doesn't appear to be the one you're using either as 14.15 should support the optional chaining operator. I don't use NX so can't help you much there, but I think it's probably not working the way you think it is.
I found "node" separately in the package.json and it's 12.x. so update it to 14.x and working fine

As mentioned on this answer to a GitHub issue, you probably need to update Node from 12 (either to 14 or 16). The best way to do this is to update your package file, run npm update, then resolve dependency issues.
