AWS CDK: AWS-ec2 SyntaxError: Unexpected token '.' after update node

Question

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)

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.
