Hi. Any idea about this issue?

cdk8s import --language python
/usr/local/lib/node_modules/cdk8s-cli/node_modules/cdk8s/lib/api-object.js:28
        this.name = props.metadata?.name ?? this.chart.generateObjectName(this);
                                   ^

I got my answer and I think cdk8s docs should be updated
upgrade nodejs to version 14|16 fixed my issue

fedora

yum install -y gcc-c++ make 

curl -sL https://rpm.nodesource.com/setup_14.x | sudo -E bash - 

node -v  

v16.2.0


npm -v  

7.13.0


sudo  npm install -g cdk8s-cli
